I believe that IsDefined is only meant to check for the existance of top
level variables, for complex data types you have to use the specific
functions for each type. So here CF is trying to find out if there is a
variable named "aStruct[aField]" and brackets are illegal in cf variable
names.
In this case I think you'll have to do a 3 step process:
<cfif IsDefined("aStruct") And IsStruct(aStruct) And StuctKeyExists(aStruct,
"aField")>
..
</cfif>
</rob>

Subject: IsDefined and brackets
The following code throws a syntax error:
<cfset aStruct=StructNew()>
<cfset aStruct.aField="something">
<cfif IsDefined("aStruct[aField]")>
aStruct[aField] is defined
</cfif>
Is this just some CF quirk that IsDefined doesn't like
brackets or is there some good reason for this?
