Hello CFers, I installed the ColdFusion 2016 Update 17 (from Update 16) which came out this week and unfortunately all of my Coldbox sites are getting 500 errors when trying to load them. The line that is causing the error is as follows: `variables.thisRoute.handler = arguments.handler ?: "";` The error that is being generated in the logs is:

This issue still seems to be prevalent in XD version 32.0.22.11. XD will not see fonts added by FontBase even though every other Creative Cloud app (Photoshop, Illustrator, etc.) seems to recognize them. The workaround of activating a font in Adobe Fonts does seem to still work, even though it's annoying. Here's how you do it, just in case anyone is new to CC. 0. Make sure XD is not open. 1. Log into fonts.adobe.com and select a font. I always use https://fonts.adobe.com/fonts/gin because it's easy to remember. 2. Activate the font. 3. You should see a popup notification on Windows from Creative Cloud that the font was added. 4. Fire up XD. You should see your Fontbase fonts have been added.

Hello fellow CFers, The Stack Overflow 2019 survey was just launched. Each year they ask developers to share information about their jobs and what languages they develop in. it would be great if the ColdFusion/Lucee community would participate and let them know you're an active CFML developer. Here's the link to the survey:2019 Stack Overflow Annual Developer Survey

Thanks BKBK for the insight. I definitely agree with you and have a rule for myself to only create getters/setters if the property is public. The only exception to this rule would be for any private property that needs to have some other behavior or validation occur when set. In the case of the latter, I make sure the setter/getter is private as well so it is not exposed. e.g. Public Properties: // public getter function getName() { return variables.name } // public setter function setName( required value ) { variables.name = arguments.value } e.g. Private Properties // no getter/setter needed for something like a dependency class function init( required privateDependency ) { variables.privateDependency = arguments.privateDependency; variables.privateDependency.doSomething(); } // setter needed for private property that needs to do something when set private function setPrivateValue( required value ) { // perform validation or do something magical ... // set it to the variables scope variables.privateValue = arguments.value; }

I feel your pain WolfShade. Having to jump into an existing project with 3500+ files sounds like a nightmare. Even if the old coder documented everything and left verbose comments it would still be a daunting task to start modifying a monstrosity like that. I've noticed that many OOP and DDD approaches to development tend to lean more towards "creating more classes" as opposed to "creating more methods/functions". This generally leads to creating more CFC files and increasing the total number of files in a project. I personally don't use interfaces, but in other languages, they are highly encouraged and could easily double the number of files a project uses if you had one or more interfaces for every class/CFC. There's a podcast that I listen to regularly called Coding Blocks​ and in a past episode they discussed whether having too many files in a project is a problem or not. They also had an interesting comparison of OOP vs procedural programming techniques. One of the hosts made an interesting point that the job of the IDE is to manage your files for you so as long as they are properly organized it shouldn't really matter how many files there are. My main takeaway from the segment was that writing OOP tends to lead towards creating more files with fewer lines in each file, whereas procedural programming will leave you with fewer files but with more lines of code per file. I'm still on the journey of discovering how to develop with an OOP mindset in CFML and I'm also relatively new to the idea of MVC. Hopefully after I hammer out a few projects I'll have a clearer idea of how everything works in comparison to how I used to build apps. Thanks for your input on the subject!

I have a possible theory as to what may be wrong with the cfdirectory "list" action and why it could be timing out. The bucket I've been working with has about a hundred sub object/folders in it, with thousands of files each. I bet that the "list" is trying to get every file in the bucket (not just the root) and it is causing the timeout. I stumbled upon the following project on GitHub: https://github.com/jcberquist/aws-cfml which seems to have a more modern implementation of S3 and when requesting the files in a bucket it limits the results to 1000. I was able to use this project to successfully query a list of files from the bucket in question. Hopefully this library will also help OP with their problem as well.

I'm curious if OP ever arrived at a solution for working with Amazon S3 directly in ColdFusion 2016? I ran into a similar problem and any time I run <cfdirectory action="list"...> on a bucket or bucket sub-folder the request waits for a very long time before eventually timing out. I experimented with Joe Danziger's S3 wrapper on RIAforce (and Github: GitHub - joedanz/cf-amazon-s3: ColdFusion Amazon S3 REST Wrapper but it doesn't work with the modern version of Amazon's API. I searched Github for another project or possibly a more recent branch of this project without luck. Has anyone been able to list the contents of a bucket "directory/object" using ColdFusion 2016?

Sorry for the delayed reply BKBK. Thank you for sharing your thoughts on the subject and I think you're right. It's very easy when learning about OOP (or OOAD) to get overwhelmed with terminology and best-practices which are often misused on Stack Overflow and various programming blogs. There definitely is a lot of programming Dogma out there, and I find myself struggling with which ideals to put into practice, and which I should leave out. It has definitely been challenging to find more advanced resources on OOP/OOAD in CFML development so I often find myself reading books and articles on problem solving in other languages like JavaScript, Python, Java, and C#. I do wish Adobe would offer more resources for modern CFML development with a more OOP/OOAD mindset. For example, it would be great if they would put together write-ups on popular design patterns and how they could be implemented in a CFML application. One thing I've started using in my apps since I initially wrote my first message is the repository pattern. Even though adding a repository has added additional complexity to my project, I like the idea of adding an abstraction layer between my business logic and the database access objects. I believe that utilizing the repository also does address the concern you brought up about coupling data access with the rest of the application. I actually designed a chart that I keep nearby that I use for reference when planning out an app. The chart is designed to identify the different "layers" of an application and where each type of object should live and who it should communicate with. Here's the chart I've been using in case anyone is curious or has feedback: [caption width="999" align="alignnone"] Application layer reference chart[/caption]

Let's say you have a component with a private property (a dependency) which will be injected into the component when it is instantiated. Now, when you're working inside the component, is it considered best-practice to have getters and setters for private properties even when they will never be exposed outside of the component? I've seen some examples online in other languages (e.g. C#) where dependencies are injected and then referenced without relying on getters/setters. I haven't really been able to find a consensus on the optimal way to proceed when it comes to private properties. Here's an example of a simple component that has a dependency (dependencyExample) which exists as a private property. In this first example, I've used getters and setters which set the property when the component is instantiated (setDependencyExample()). Then, when a method (doSomething()) needs to utilize the property, the getter (getDependencyExample()) gets triggered in order to gain access to it. https://paste.ofcode.org/ubhMPgSZR3rvExxES6yLHB Now here's a second example where the private property does not have any getters/setters. Instead, the property is set and accessed directly via the variables scope: https://paste.ofcode.org/JjbUWc6PBMez42i8UVgHn5 It seems to me that if you don't use getters/setters for private properties, you wind up with potentially much leaner code (if you have a lot of private properties). However, I'm not sure if this way of doing things violates some best-practice rule of OOP. I would love to hear your thoughts on the matter.

Based on my reading, the Repository pattern is frequently used to create an abstraction layer between an application's business logic/entities and the data/persistence layers (i.e. the database). However, most of the examples I've seen online on how to implement these patterns are in C#, Java, or other languages. Additionally, they always seem to be using some type of ORM like Entity Framework. [caption width="543" align="alignnone"] How a repository works. Credit: Microsoft[/caption] I'd like to learn more about the Repository pattern and evaluate how I can utilize them in my OOP CFML app development. I'd also like to see examples of how a repository might be used in CFML without an ORM. I wonder if I would need to create my own "data mapping object" which would help translate my entities into the individual data points before sending them off to my DAO's for persistence. Does anyone have any experience with this subject and/or have links or examples of how to implement these patterns in CFML? I feel like I'm a bit stuck on how to proceed here.

Thanks for the reply, Charlie. It's funny you mention the Matt Gifford book as that is the first ColdFusion OOP book I read. The Amazon link didn't work for me but you can also find it on PacktPub here. I then followed up with reading the Adobe ColdFusion Anthology by Michael and Judith Dinowitz which covers many topics including some OOP patterns however I didn't feel that book went into as much detail as I would have liked on the subject of OOP. I then decided to read a book about OOP in JavaScript (also on PacktPub ) to get a different perspective on the subject. I found that book to be extremely helpful in teaching me terminology and new concepts even though Javascript is very different than CFML. I haven't found many modern resources or sample code for OOP/DDD development with CFML these days so I've turned to looking at examples for other languages like Python or Java.

I've been reading a lot about object oriented programming (OOP) and domain driven design (DDD) over the past few months. I've also been trying to wrap my head around how I can implement OOP coding styles into my daily CFML application development. Most of the time you'll see OOP/DDD applied towards solving rather complex problems, which makes sense in terms of using it for production purposes. However, when trying to learn a concept sometimes it makes sense to take something simple and make it a little more complicated in order to learn. In other words, I need to learn how to walk before I can run. What I've done is set up a simple model for a user registration system that will be used on a web site. I'm sure we've all built tons of these things - a user visits a web site where they are asked to enter their name, email address, password, etc... My goal was to take what I've learned about OOP so far and apply it to a scenario like this. In my reading about OOP I came across a concept called an "anemic domain model" which some people consider to be an anti-pattern. An anemic domain model, as I understand it, is basically using your entity objects (the "user" object in this case) as dumb "bags of getters and setters". Essentially this means your objects don't contain any business logic and aren't all that different different than a standard CFML struct. Many people argue that entities should contain behavior. The difficult part for me is understanding which behavior belongs in an entity, and which belongs in a service. If you add too much behavior in an entity, you could wind up with a massive object that is trying to do too many things at once (a "no-no" if you're following SOLID principals). Walking that thin-line has been a challenge for me. Another thing I came across (special thanks to Hal Helms and Sean Corfield) that really struck a cord with me was that an entity object should never be allowed to exist in an invalid state. I really liked that idea and felt that if I could ensure my entities were never invalid, I could write better code with fewer potential for bugs. My takeaway from this concept is that from the time you create an entity object to the time it evaporates at the end of a request, it should never ever exist in an invalid state. For example, if you had a business rule stating that all users must have an email address. You would need to design your User entity so that emailAddress could never be anything other than a valid email address. So how does all this apply when you're talking about a user registration form? Here's a diagram I made of my model:https://i.imgur.com/NoxX0Eh.png Components: UserService The user service is a singleton object which assists with the getting and saving user data. An important thing to note about a singleton object like this is that it does not manage state! What this means is that this service should be accessible and used by other people using the application. Typically I like to store singletons in the application scope or in a factory which lives in the application scope. UserDAO The user DAO (data access object) is what actually communicates with the database. This object is responsible for running the SQL required for getting, adding, saving, records from the database. This object is injected into the UserService as a dependency. By injecting the object and making it private ensures that only the UserService can make calls to it. User The user object represents an individual user record in the database. This object is also known as an "entity" and contains a specific instance of a user's data. For example, first name, last name, etc. Note: In an attempt to move away from an anemic domain model, you can place business logic in your entity objects. For example, if you wanted to have a requirement for password strength or some other business logic you could include it here. You might also have some logic insuring that the emailAddress field contains a valid looking email address. The "business logic" I've included ensures that the user entity object can never exist in an invalid state. Some people call entities like this "rich domain models" or "rich entities". RegistrationForm The registration form object is also an entity. This object will contain the data for the actual form fields (input boxes, etc...) as well as validation logic to ensure that the data is valid and safe to be inserted into the User entity object. Think of the registration form object as a "proxy" that lives in between the user's input and the actual object they are trying to add or update. You might be asking yourself right about now, "Why do we even need a separate object to hold the form data? Couldn't we just add the data directly to the user entity object?" The reason we use the RegistrationForm object is because a registration form can exist with no data, partial data, or even drastically invalid data. Think about it... when you first visit a registration form all of the text boxes are empty. Is the form in an invalid state? No. You can type anything you want into the name fields, or you could leave them blank. You could type gibberish into the email address field, or make a password with only 1 character. The form, still exists without throwing an exception error. In other words, a form is simply something that accepts user input. If you tried to add a gibberish email address into the User entity object the User entity object would exist in an invalid state. That would be very bad. To prevent invalid states from occurring gracefully, the RegistrationForm entity has some business logic thrown into it, the validate() method. The validate() method checks to see if the data contained within itself is suitable to be placed within a User entity object. If the validation passes, the User entity is updated. If validation doesn't pass, the form shows itself to the user again so they can correct their inputs. Here's a diagram showing how that process works: So there's my attempt at taking something as simple as a user registration form and applying my understanding of OOP principals. I'd love to hear your thoughts on my approach, how you'd handle things differently, and if you have any suggestions for me moving forward. One thing that I'm still wrestling with is the idea of the "anemic domain model" and how much (and what kind) of behavior to include in my entities. I can think of some examples where an object might have a bunch of behavior or business logic and it would make sense to break that out into several different services otherwise your entity object code would be massive and unmanageable. Thanks for reading and I look forward to hearing your thoughts and criticisms.

Thanks Charlie. I also took a look at the cfDocs (https://cfdocs.org/writedump) and it suggests you can pass a `format` attribute which might do the trick. Unfortunately it doesn't work for me on ColdFusion 2016. Non-Working Example: <cfscript> myVar1 = "apple"; myVar2 = "banana"; writeDump( var = "#myVar1#<br>", format="html" ); writeDump( var = "#myVar2#<br>", format="html" ); </cfscript> This might be a nice thing for Adobe to add as a possible feature in the future. In the meantime, perhaps a custom UDF will do the trick.

This is an old thread but it seems that some users are still bothered by Dreamweaver's performance. My solution to the problem may not be what my fellow Dreamweaver users want to hear but I actually moved away from using Dreamweaver altogether. Instead I've moved on to a commercial IDE called Intellij IDEA. When I first moved over to IDEA I was pretty indimidated by the interface and all the menus. IDEA definitely does not hold your hand through web design/development like Dreamweaver does. However after using it for 2+ years now I can safely say that it is by far the best web development tool I have ever used, especially if you do any type of ColdFusion (CFML) or JavasScript development. One way you can think of an IDE is that it is like Dreamweaver except there is no "design view". Instead, you will need a web browser to preview your pages to see what they actually look like. However, IDEA does have a deployment feature which works like Dreameweaver's FTP functionality and will allow you to sync your files with one or more remote web servers. There are other IDEs available as well, Eclipse, CF Builder (basically Eclipse with an Adobe skin), and others. However after experimenting with many different ones I decided to stick with IDEA. If you're experiencing Dreamweaver performance problems perhaps it means that you've graduated beyond building basic web pages in HTML and are ready for a more robust solution. IDEs may not be for everyone but I know that they have really taken my web apps to the next level, taught me a lot about coding best-practices, and helped keep all my web projects organized.

Thanks @Steve and @BKBK, you both have great points. After reading your responses I decided to scan StackOverflow to get opinions on how people tackle this in other languages (Java, C++, etc...). I discovered an interesting discussion where a developer was having a hard time with his/her DAO - specifically when updating data. Basically the issue boiled down to a "race condition" where multiple users could be editing a single record at a time but editing different fields. Passing the entire bean to the DAO could cause your web application to overwrite another user's changes to the bean object! Yikes! Timeline Example: User 1 updates field A in the bean User 2 updates field B in the bean User 2 passes bean to DAO, DAO updates all fields. User 1 passes bean to DAO, DAO updates all fields. In the above example, User 2's updates to field B would be overwritten by user 1! I couldn't find any concrete way to avoid this situation with standard CRUD operations in a DAO. Some users suggested locking or using some type of transnational control in the service layer but that was a little over my head. However it got me wondering if the bean object itself could be smart enough to return an object containing only the changed fields? This could easily be accomplished with a small utility class that every bean could contain. So for example, lets say you have a User bean, and you just want to update FirstName: 1. The bean object when instantiated would have a sub-class of utilities inside it I'm calling "BeanUtilities". 2. During the constructor the bean would run the backup() method from the utilities class to make a copy of all of the bean data and stores it in the instance. 3. The user runs the setFirstName("Steve") on the bean which changes the FirstName of the object from "Dave" To "Steve". 3. The user wants to then save the data via the service class which passes the data to the DAO. The DAO object would know that all beans have a method called getChanges() which would spit out an object containing only the key/value pairs of fields that were changed in the bean. The DAO could run this method and then update only the relevant fields. EDIT: Note you could also have an argument somewhere which would "force" a full save overwriting all fields just in case the business logic demands it. Perhaps this violates some concrete rule of OOP but at first glance this type of setup appears to let us have our cake and eat it too. I'd love to hear your thoughts on this approach.

Thanks for the reply Steve. That is true I could use the <cfcomponent> "accessors" property and set it to true. However something feels unsettling to me by referencing values from my bean using method calls instead of variables. <cfoutput>#myBean.value#</cfoutput> vs <cfoutput>#myBean.getValue()#</cfoutput> Perhaps my wariness comes from lack of experience using bean objects and it is just something I need to get used to. I really like your idea of having a property for "dirty" which would basically detect whether a bean has been modified from the original constructor. Of course this means all of my setters would need to be hard coded into the bean which would require a ton of methods for data with many columns.

I just finished reading a book on introducing Object Oriented Programming (OOP) in ColdFusion. I found the book to be very enlightening on many levels however I was left with some questions and there didn't seem to be anywhere to go after the book to learn more advanced topics or to seek clarification or more information. I may be creating a few questions on this forum over the next few days/weeks with OOP related subjects and ColdFusion that I would love your feedback and opinions on - especially from people that have experience working with OOP. This question pertains to bean objects and storing subsets of data within them. I understand the basic concept of storing information within a bean to represent a single record of information. For example, you might have a "User" object bean which stores information like firstName, lastName, emailAddress, etc... However I find that often times you may want to store a subset of data within your object. For example, you might let users store one or more mailing addresses to their record. I like to think of these subsets as "attachments" to the primary record. They come from a different table in the database but they are very much a significant part of the root data. In the past when I'm using procedural programming I store my user data in a structure object and then include a separate key for each subset of data which might contain a nested query like this: As you can see in the above screenshot I have an object containing the information on the user as well as a subset of data (attachments) for each address associated with the user. Now I suppose this type of thing could be accomplished from within the bean object. Technically you can store anything you like in there... but does storing a sub-query of data violate the entire concept of a bean? Or is there a graceful way to accomplish this that I haven't encountered yet? One way I could accomplish this is by using a Service Layer to grab the user data from the DAO and then grab all of the addresses from a Gateway object and shove all of them into the bean like this: I'm still new to using UML so please forgive me if I've used the wrong symbols. In the above example the client would request getUserByID() from the UserService object which would return a bean object containing the data from the userDAO object and the AddressGateway object. Is this the correct way to go about this type of data retrieval? The only problem I can see with this type of bean comes when you want to update the user record using some type of DAO updateUser() method. In this case, the bean contains an "addresses" query object which isn't part of the "users" table. I suppose having extra data in the bean won't hurt an SQL update statement but it does involve passing extra data to a CRUD method that doesn't need to be there.

I found the book to be very enlightening on many levels however I was left with some questions and there didn't seem to be anywhere to go after the book to learn more advanced topics or to seek clarification or more information. I may be creating a few questions on this forum over the next few days/weeks with OOP related subjects and ColdFusion that I would love your feedback and opinions on - especially from people that have experience working with OOP. This question pertains to Data Access Objects (DAO) and best practices or recommendations for using them in a ColdFusion application. I'll be using a generic "User DAO" as an example. Historically whenever I've created a DAO method that updates a database table within a CFC I've always included a <cfargument> for every single column that can be updated in the database. Then within my method I check for the existence of an argument and if passed, I update that column. The end result is an update method which only updates database columns that were passed as arguments. This has always made sense to me for example if the user wants to update their password you can simply update that one field. Here's an example method to show what I mean: <cffunction name="updateUser"> <cfargument name="usersID" type="numeric" required="yes" /> <cfargument name="firstName" type="string" required="no" /> <cfargument name="lastName" type="string" required="no" /> <cfargument name="emailAddress" type="string" required="no" /> <cfargument name="passwordHash" type="string" required="no" /> <!--- update the database ---> <cfquery datasource="#application.dsn#"> UPDATE Users SET DateModified = #createODBCDateTime(now())# <!--- go through each column, check to see if an argument was passed and if so, update the column ---> <cfif structKeyExists(arguments, "firstName")> , firstName = <cfqueryparam cfsqltype="cf_sql_varchar" value="#arguments.firstName#" /> </cfif> <cfif structKeyExists(arguments, "lastName")> , lastName = <cfqueryparam cfsqltype="cf_sql_varchar" value="#arguments.lastName#" /> </cfif> <cfif structKeyExists(arguments, "emailAddress")> , emailAddress= <cfqueryparam cfsqltype="cf_sql_varchar" value="#arguments.emailAddress#" /> </cfif> <cfif structKeyExists(arguments, "passwordHash")> , passwordHash = <cfqueryparam cfsqltype="cf_sql_varchar" value="#arguments.passwordHash#" /> </cfif> WHERE UsersID = <cfqueryparam cfsqltype="cf_sql_integer" value="#arguments.usersID#" /> </cfquery> <cfreturn true /> </cffunction> In the book, the author shows a similar method however instead of passing individual arguments, he suggests passing a single bean object to the method and then updating the data. Here's an example: <!--- UPDATE ---> <cffunction name="updateUser"> <cfargument name="userBean" type="any" required="yes" /> <!--- update the database ---> <cfquery datasource="#application.dsn#"> UPDATE Users SET DateModified = #createODBCDateTime(now())# , firstName = <cfqueryparam cfsqltype="cf_sql_varchar" value="#arguments.userBean.getFirstName()#" /> , lastName = <cfqueryparam cfsqltype="cf_sql_varchar" value="#arguments.userBean.getLastName()#" /> , emailAddress= <cfqueryparam cfsqltype="cf_sql_varchar" value="#arguments.userBean.getemailAddress()#" /> , passwordHash = <cfqueryparam cfsqltype="cf_sql_varchar" value="#arguments.userBean.getPasswordHash()#" /> WHERE UsersID = <cfqueryparam cfsqltype="cf_sql_integer" value="#arguments.userBean.getUsersID()#" /> </cfquery> <cfreturn true /> </cffunction> While this makes sense because you can pass a single object as an argument instead of a bunch of arguments it doesn't make sense to me to update database columns for data that hasn't necessarily changed or that the calling service object wasn't designed to update (again like updating a password). I've also seen discussion online for other languages where people seem to discourage writing methods with a lot of arguments but I haven't been able to figure out why. My only guess is because many other languages don't allow for passing named argument collections (like CFML does) so you'd have to be very careful about the order you submit your arguments. I'd love your opinion on whether creating a DAO object method that accepts a single bean object is better than a method requiring only the arguments that actually need updating.

I just finished reading a book on introducing Object Oriented Programming (OOP) in ColdFusion. I found the book to be very enlightening on many levels however I was left with some questions and there didn't seem to be anywhere to go after the book to learn more advanced topics or to seek clarification or more information. I may be creating a few questions on this forum over the next few days/weeks with OOP related subjects and ColdFusion that I would love your feedback and opinions on - especially from people that have experience working with OOP. My questions pertain to the use of bean objects when working with a single record of data. For sake of these questions lets work with a simple "User" object that contains information about a person like firstName, lastName, emailAddress, and a passwordHash. Question 1: What is the purpose of using the <cfproperty> tag? Is it only for introspection purposes when you run <cfdump> on the component instance or does it actually have an impact on the component and the data within it? In fact, the only time you can see the properties when you dump the component is if it has a matching getter method. Question 2: Why is it so important to create public getters/setters within a bean object when it would be easier to just access the properties of the bean directly? In order to clarify what I mean, I created two components below, user.cfc and user2.cfc. User.cfc is a bean object that has getters/setters for each <cfproperty> (note: I left some getters/setters out to keep this example brief and please excuse the indentation as I can't seem to get the forum editor to display my code very well): <cfcomponent displayname="user" hint="I am the user class" > <cfproperty name="firstName" type="string" default="" /> <cfproperty name="lastName" type="string" default="" /> <cfproperty name="emailAddress" type="string" default="" /> <cfproperty name="passwordHash" type="string" default="" /> <cfset variables.instance = structNew() /> <!--- Constructor ---> <cffunction name="init" access="public" hint="I am the constructor method" > <cfargument name="firstName" required="false" type="string" hint="I'm the first name of the user" /> <cfargument name="lastName" required="false" type="string" hint="I'm the last name of the user" /> <cfargument name="emailAddress" required="false" type="string" hint="I'm the email of the user" /> <cfargument name="passwordHash" required="false" type="string" hint="I'm the hashed password for the user" /> <cfscript> variables.instance.firstName = arguments.firstName; variables.instance.lastName = arguments.lastName; variables.instance.emailAddress = arguments.emailAddress; variables.instance.passwordHash = arguments.passwordHash; </cfscript> <cfreturn this /> </cffunction> <!--- SETTER: FirstName ---> <cffunction name="setFirstName"> <cfargument name="firstName" required="true" type="string"> <cfset variables.instance.firstName = arguments.firstName /> </cffunction> <!--- GETTER: FirstName ---> <cffunction name="getFirstName"> <cfreturn variables.instance.firstName /> </cffunction> <!--- Memento returns the instance data ---> <cffunction name="getMemento"> <cfreturn variables.instance /> </cffunction> </cfcomponent> The following code instantiates the component, dumps it, and then updates the firstName of the user object. Finally it dumps the data in the object. <!--- instantiate our component ---> <cfset user = createObject("component", "cfc.user") .init( firstName = "John", lastName = "Smith", emailAddress = "test@test.com", passwordHash = "xxxx" ) /> <!--- Dump the component for introspection ---> <cfdump var="#user#" /> <!--- dump our instance ---> <cfdump var="#user.getMemento()#" label="default instance" /> <!--- change the firstName ---> <cfset user.setFirstName("Jane") /> <!--- dump our instance again ---> <cfdump var="#user.getMemento()#" label="updated instance" /> <!--- dump the first name ---> <cfdump var="#user.getFirstName()#" /> This gives us the following output: In the second example, users2.cfc, I'm creating a much simpler CFC where the properties are stored in the this scope to allow direct access to the variables without the need for getter/setter methods. <cfcomponent displayname="user" hint="I am the user class" > <cfproperty name="firstName" type="string" default="" /> <cfproperty name="lastName" type="string" default="" /> <cfproperty name="emailAddress" type="string" default="" /> <cfproperty name="passwordHash" type="string" default="" /> <cfset this.instance = structNew() /> <!--- Constructor ---> <cffunction name="init" access="public" hint="I am the constructor method" > <cfargument name="firstName" required="false" type="string" hint="I'm the first name of the user" /> <cfargument name="lastName" required="false" type="string" hint="I'm the last name of the user" /> <cfargument name="emailAddress" required="false" type="string" hint="I'm the email of the user" /> <cfargument name="passwordHash" required="false" type="string" hint="I'm the hashed password for the user" /> <cfscript> this.instance.firstName = arguments.firstName; this.instance.lastName = arguments.lastName; this.instance.emailAddress = arguments.emailAddress; this.instance.passwordHash = arguments.passwordHash; </cfscript> <cfreturn this /> </cffunction> <!--- Memento returns the instance data <cffunction name="getMemento"> <cfreturn variables.instance /> </cffunction>---> </cfcomponent> I then instantiate the component just like the first example however I can then update the properties of the user object by directly getting and setting them without any special methods: <!--- instantiate our component ---> <cfset user2 = createObject("component", "cfc.user2") .init( firstName = "John", lastName = "Smith", emailAddress = "test@test.com", passwordHash = "xxxx" ) /> <!--- dump the component for introspection ---> <cfdump var="#user2#" /> <!--- dump our instance ---> <cfdump var="#user2.instance#" label="default instance" /> <!--- change the firstName ---> <cfset user2.instance.firstName = "Jane" /> <!--- dump our instance again ---> <cfdump var="#user2.instance#" label="updated instance" /> <!--- dump the first name ---> <cfdump var="#user2.instance.firstName#" /> This produces the following output: So why do we need to go to all the extra effort of creating getter/setter methods in bean objects when we can access the properties directly as if it were a normal structure? Other than for introspection reasons I can't figure out why beans need to be built this way?

Thanks for the reply Jon, That's great you aren't experiencing any performance issues. My test setup involved running it on my Desktop and Laptop both running Windows 10 (x64). I don't have access to a Windows 7 machine right now so perhaps DW 2017 performs better on Windows 7? Either way, the more info we gather the better! I appreciate it!

Hello All, I spent some time and came up with an experiment that we can all run to re-create the DW 2017 sluggish behavior problem. Ideally you'll want to run the experiment with both DW 2017 DW 2015 installed on your machine to compare performance. Hopefully someone at Adobe will also run this test (wink wink, nudge nudge)! Here's how to run the experiment: 1. Load up Chrome and open a new incognito window. 2. Visit the web site https://adwords.google.com (this is the Google AdWords home page. It will be our testing page) Side note: The reason I picked this page is because it's got a lot going on here and should be enough to stress the HTML parser and show a measurable difference in performance between DW versions. You could run this test with any other complex HTML page if you want. 3. Save the web page to your desktop by clicking CTRL + S (or click the browser menu > more tools > save page as...). Make sure to save the complete web site in the save dialog options. 4. Once you've saved the page to your desktop, right click on it and open it in Dreamweaver 2017. 5. Play around with the source code, experiment between code view, design view, split view, etc. Warning: this makes my copy of DW run at a snail's pace and I have a pretty beefy machine. 6. Now close DW 2017 and open the same file in DW 2015. 7. Again, play around with the source code, experiment between code view, design view, split view, etc. Notice any difference? What does this test prove? Well well all know that the HTML parsing engine that is in DW 2017 is different than 2015 and it's obvious that the new engine can't handle complex web pages with many external files referenced as well as the old version of Dreamweaver did. This test was designed to make Dreamweaver work hard intentionally and probably isn't a realistic work example. You may note that If you decide to run this test without saving the "complete web site" and instead just save the HTML you will notice that DW performs much better. I believe the key to this is the number of included external file references (.js, .css, etc...) that DW has to parse and deal with. Are there any workarounds? Not really. However feel free to experiment with your DW 2017 configurations. Experiment with turning off code coloring, validation, etc... maybe there's a magic bullet that we can temporarily disable until Adobe comes up with a fix. One thing you could do is temporarily comment out or remove your external javascript and css files. Assuming that is the problem here it may make DW 2017 perform better. Hope this helps! Feel free to post your test results and thoughts.

Dreamweaver CC 2017 is also incredibly slow for me and I have a pretty fast machine (i7-4770K @ 3.50GHz and 16GB RAM Windows 10 x64). It also tends to lock up frequently when I copy/paste code into Code view from another source or when switching back and forth from code/design view. Note: I didn't have these problems with the recent Dreamweaver beta which I thought performed pretty well. I've tried turning off code linting with no effect and I'm still brainstorming possible ways to improve performance. Hopefully Adobe will get enough complaints and either fix it or provide information on how users can fix it themselves.

I recently ran into this same issue on ColdFusion 2016 (update 3) on Windows 10 and also on Windows Server 2012. I can confirm based on what previous posters have said that when IIS rewrite is enabled the wrong HTTP response headers are sent to the browser. Additionally, the wrong content length is also sent. I believe that this is a connector issue and not IIS. Here is an example of the proper response header when accessing a file (e.g. /test/file.cfm?filesID=1) Cache-Control:no-cache, no-store, must-revalidate, max-age=0 Content-Disposition:attachment; filename="Wag_Cameras_Administration_Documentation_10.pdf" Content-Length:207349 Content-Type:application/unknown;charset=UTF-8 Date:Fri, 18 Nov 2016 01:16:02 GMT Expires:Thu, 01 Jan 1970 00:00:00 GMT Pragma:no-cache Server:Microsoft-IIS/10.0 X-Powered-By:ASP.NET Here's an example of the invalid response header when accessing a file via IIS rewrite (e.g. /test/file/1/) Cache-Control:no-cache, no-store, must-revalidate, max-age=0 Connection:close Content-Disposition:attachment; filename="Wag_Cameras_Administration_Documentation_10.pdf" Content-Length:1284 Content-Type:application/unknown;charset=UTF-8 Date:Fri, 18 Nov 2016 01:16:39 GMT Expires:Thu, 01 Jan 1970 00:00:00 GMT Pragma:no-cache Server:Microsoft-IIS/10.0 X-Powered-By:ASP.NET There are two things wrong with the response header. The first is that "Connection: close" has been added as well as an incorrect content-length which is why the file you wind up downloading is a corrupted (incomplete) version of the PDF you wanted. I created a bug in the adobe bugbase here: Bug#4197947 - <cfcontent> fails to serve PDF files when using IIS rewrite Please vote for it. Unfortunately since this issue is difficult to replicate if anyone can add their own replication code to the bug I'm sure it would be a big help to the dev team.

Hello CF Community, I recently upgraded from ColdFusion 10 to ColdFusion 2016 and I noticed that I can no longer access any pages that live in any folder named /api/. For example: www.mysite.com/api/index.cfm now returns a 500 error "Application could not be found". See the following screenshot: http://i.imgur.com/axFVekv.png Note: when I installed ColdFusion 2016 I didn't select to install the API Manager service nor do I need it. Thanks for your help!

I asked this question over in stack exchange as well but I'm curious to hear the opinions from my fellow CF developers to see if anyone has any insight on this. If you'd like to chime in on the stack exchange thread instead, click here. I'd like to know the correct/optimal way to create a database schema for a ColdFusion based online store that allows customers to pay their invoices in full or in X number of monthly installments. I've played around with a couple different ways of accomplishing this and the first issue that came up for me was whether the scheduled payments should be calculated on the fly (by ColdFusion) or whether each scheduled payment should exist as a record in a database. I'm going to assume that the best-practices way would be to have a separate database table to store these scheduled payments (even if it's just one record for a pay-in-full situation). Here's the database schema I have been playing around with: The current plan is to create a single invoice when an order is placed. Then I would create X number of scheduled payments records depending on how many payments the customer is going to use to pay off the invoice. Then as payments come in, I will add the record to the payments table and then create a joining record in the r_ScheduledPayments_Payments table with the amount that was applied towards the scheduled payment(s). Is this how most online stores, e-commerce applications or banks handle this type of setup? In a way it's kind of like a bank loan so perhaps a banking model would be appropriate. I couldn't find any other decent examples online so you're seeing my first draft of a possible solution. I'd love to hear ideas on how to best accomplish this from a CFML dev's perspective.
