No! Just change your isdefined:

cfif isDefined(form.mytest)

If you need mytest to be dynamic (ie, its a pointer to the field name),
then you would use

cfif isDefined(form.#mytest#)

Todd
Why not just do:
cfif isDefined(form.mytest) ?

variable[] isn't really a true variable name.  Think of [] as an operator 
like + and -.

I think that MX fixes that bug.

Todd, I do Isdefined('form.mytest')  all the time and it works well.  I
think you should use structkeyexists( ) if you want to use the bracket
syntax.

Re: IsDefined() bug?

2002-10-25 Thread Stephen Moretti 
 Use the evaluate function


Do you really want Ray Camden on your case???  ;oD

FWIW : that won't work anyway.
   . with IsDefined(evaluate(FORM['mytest'])  you get the same response as
Todd's code.
   . with IsDefined(#evaluate(FORM['mytest']#), CF evaluates
FORM['mytest'] out to its content, which will fail if the variable is not
defined.
   . with IsDefined(evaluate(attributes['fuseaction'])) you get the same as
with #'s in the isdefined.

As Todd says, he should be using StructKeyExists() to see if mytest is in
the struct FORM or Ray's example of cfif isDefined(form.#mytest#)

Regards

Stephen

  I
 think you should use structkeyexists( ) if you want to use the 
 bracket
 syntax.

Note that structKeyExists() and isDefined() have slightly different 
meanings.

If you have a struct and you assign a Java null to one of the keys, 
then structKeyExists() will yield true but isDefined() will yield false.

It's an edge case but it's something to watch out for...
