use createUUID() as a form variable

All thanks for the replies.

I have fixed my problem using 'structKeyExists' instead of 'isDefined'.

Next thing is to google for the difference between both, but that's the funny part

The other two answers are also something to keep in mind.

The problem is that variable names can't contain hyphens.

I got caught by this when I was using cold fusion uuids for the primary key of a table.  In my case, I actually wanted to append the primary key values to the end of form variables, so I used replace() to strip out the hyphens.

The way you described what you are doing, you should be able to create the uuid on your action page.

There are multiple answers at different levels.  The answer to your immediate question is to either not use UUID or to use replace() to parse out the dashes.

The next answer needs more information from you as to why you are creating a unique ID for the formfield name.  If we know what you are really trying to do, we can give you some hints.  For example, if you are actually creating a number of similar formfields, based on data coming back from a db query, then that's not uncommon at all.  The most common way of handling that is to imbed the value of each row's key into the formfield, maybe along with the database columnname in cases where you are creating formfields for multiple columns of each row (common in a CRUD app).  Seperate those parts of the formfield with a character like an underscore, and you can parse them out on the processing page.

The more we know about what you're trying to do, the more we can help.
