There are good reasons why an IDE removes import statements which are not used in a piece of code. It is not very productive to type import statements and it is better to rely on code completion. It was painful to watch the demonstrator keep undoing the removal of the import statements. I would recommend either removing the typing of the import statements or just highlighting it at point when the IDE has imported it for you.

I have problems even if I fix namespace issue that edgarTL pointed. After I change a value after of evaluation field and click on another field I get this: ReferenceError: Error #1069: Property text not found on EmployeeDirectory_inlineComponent1 and there is no default value. at mx.controls::DataGrid/itemEditorItemEditEndHandler()[E:\dev\gumbo_beta2\frameworks\projects\framework\src\mx\controls\DataGrid.as:5240] at flash.events::EventDispatcher/dispatchEventFunction() ..... Is it a beta code bug ? And the last part "Using a component item renderer" works fine to the last step 22 but if I click on a evaluation field, I get another bunch of nasty errors. May be it supposed to work like this but I wouldn't call it "working example".

Case Study: One Array Source For Two ArrayCollection http://myprog.wordpress.com/2009/09/04/case-study-one-array-source-for-two-arraycollection/ My conclusion is that there is very few reasons to copy an ArrayCollection (and it’s source). If you need 2 views on an Array, for instance: - one view sort by id to quickly retrieve an object (often the one in your ModelLocator for Cairngorm) - one view for a dataProvider (different sort and filter can be applyied. often in a custom control such as a filtered DataGrid). Create 2 ArrayCollections that share the same Array source. When you update the source Array both Collections changes but you can still apply filters and sorts on one collection without modifying the other.

I guess it IS a bug. But if you use code completion the two import statements will be added automatically as soon you complete the two return statements (using code completion).

Correction, it should be hight="440". Also, on the step 10 at the begging I had to make height="207" so buttons on the first 2 panels would be aligned.

Step 3 in "Using text layout properties" : height="439" and it would make third panel the same size as other two. and if you add 'borderVisible="false"' , say , on the step 12, it would make the panel even more like the first two.

Please don't use the same name for an object as a class in your examples: var query:OLAPQuery = new OLAPQuery; That makes it harder to distinguish when you're calling an instance method versus a static class method.

I concur with RJMR4. I'm a report developer and I constantly work with people who want to see both the high-level view and the details. Combining those views with expand/collapse or drill-down features is probably the easiest way to keep large data sets organized.

Hi, The specific objectives that are under that category are: - Create and use custom components. (By using MXML and ActionScript) - Transfer data between components by using data bindings. - Create, handle, and dispatch custom events. - Handle framework events. - List and describe the differences between model, view, and controller code in a Flex application. Let me know if you have other questions. Thank you, Jim

I guess the problem is that this excersize uses the TextInput controller instead of the TextArea controller. Using the TextArea controller (in the spark namespace) fixes the problem.

Current code doesn't handle the case when endDate selected first and startDate selected after. If you remove the first condition in the if () clause then the code would handle both cases.

Careful with getQualifiedClassName - you would expect it to return something like "path.to.package.MyClass", but instead returns "path.to.package::MyClass" - this should be documented here. It's also a bit confusing, seeing as you don't use :: to instatiate a class when you have the fully qualified class name.

Mon, 16 Nov 2009 18:52:34 +0000

I'm noticing that in FB4, any Vector import is automatically removed by code cleanup and the SWFs/SWCs still build fine in that environment. However, in either FB3, Eclipse w/Flex plugin, or (at least older versions of) ant builds, this same code will get a compiler error. Can someone explain why this is, and what I should look for in the "problematic" environments to make them capable of also compiling w/out the import, if this is at all possible?

If I use the flex-config.xml or an additional config file with the following: -load-config+=compile_config.xml that contains my constants, the compiler throws an error when using conditionals for class definitions: A file found in a source-path must have an externally visible definition. If a definition in the file is meant to be externally visible, please put the definition in a package. MyApp CondCon.as CondCon.as has two conditional class definitions - do I need to do anything additional to enable conditional class definitions in Actionscript 3 projects - define a namespace in the project anywhere or anything else? The conditional values are available if I use additional compiler arguments in the project properties box, but not in the external xml config files: -define=CONFIG::debug,true OR -define+=CONFIG::debug,true

This is a good tutorial. It makes Lynda.com look like a beginners effort. I am not even done the first day and I have picked up very important tips necessary to develop Flex Apps. Looking forward to the other days. Please keep up the excellent work. In addition, the entire tutorial is very clear and presened very professionally. This will certainly help anyone get off the ground in developing Flex Applications.

I am not sure exactly what "all component properties specified on the MXML tag have been initialized" is intended to mean, but my initial interpretation of it was wrong and I doubt I am the only one. I had assumed this meant any properties you've set in MXML will be populated with the values you have provided, but this is not the case. If you have something like , someProp will usually be null when initialized() is called. That can obviously cause problems, and I think the docs should be made more clear.

Hi, can anyone explain how what is the meaning of the property maxPauseBufferTime? I'd like to buffer approx 10 seconds of FLV having the bufferTime set to default (i.e., 0.1 second). I'm experimenting with the following code: var nc:NetConnection=new NetConnection(); nc.connect(null); var ns:NetStream=new NetStream(nc); ns.maxPauseBufferTime=10; ns.play("video.flv"); ns.togglePause(); var v:Video=new Video(); addChild(v); v.width=200; v.height=150; v.attachNetStream(ns); stage.addEventListener(KeyboardEvent.KEY_DOWN,stisk); //--- function stisk(e:KeyboardEvent):void{ if(e.shiftKey){ ns.togglePause(); }else if(e.ctrlKey){ trace(ns.bufferLength+"\t\t\t\t"+ns.bufferTime); } } Whenever I trace during the pause mode to see how many seconds were loaded the result is always the same: approx 0.2 (twice the size of the buffer). ANY IDEAS what I'm doing wrong that it doesn't work?? Thnx Tom

Jag, I think this is an issue about run time performance... The objects on the second and third accordion panes are created and stored in memory at startup, but are not rendered until the pane is completely visible... If you want the objects to be animated during the accordion's transition, you'll probably have to extend the accordion class. Unfortunately, I don't have an example of that, but maybe the folks in the Adobe forums or on the Flexcoders mailing list can help? Let me know if you need links to these resources, matt horn flex docs

The creationPolicy="all" for the accordion does not work as I expected. In the last example if you click on one of the leafs the contents of the leaf is only rendered AFTER the accordion has finished it's change-leaf animation. The second time you open a leaf the contents are displayed as expected and the contets are shown sliding up(or down). Is there some other way to force flex to prerender the contents to achive the desired smooth effect the first time?

Fri, 13 Nov 2009 12:34:43 +0000

How do I find out if one class is the subclass of another class? This is the trivial case: var superlass:Class; var potentialSubclassInstance:*; trace(potentialSubclassInstance is superlass); If I have two objects, I also know how to do it: var superclassInstance:*; var potentialSubclassInstance:*; trace(potentialSubclassInstance is (superclassInstance as Object).constructor); But how do I do it if I only have two classes and cannot instantiate the potentialSubclass? I helped myself by writing E4X queries for the result of describeType(potentialSubclass), but I am sure there must be an easier, more elegant and more performant way of doing it. trace(potentialSubclass != superclass && describeType(potentialSubclass).factory.*.(name() in {"extendsClass":0, "implementsInterface":0} && @type == getQualifiedClassName(superclass)).length > 0)
