I have the following problem, I want to find out whatever the variable 'this.fieldArray[isUUIDpresent].selectArray' is Defined.
'this.fieldArray' is an array of structures. One member of some structure could be 'selectArray' I cannot do it with isDefined() function by doing this isDefined("this.fieldArray[isUUIDpresent].selectArray") since I get this:
"Parameter 1 of function IsDefined, which is now "this.fieldArray[isUUIDpresent].selectArray", must be a syntactically valid variable name. "
Error message is correct - it exposes limitation of isDefined() (cannot check existence of complex data type variables).
Thus, what I need is a function isArrayPositionDefined() or something like that. Currently I go about solving this problem using something like this:
<cftry>
<cfset temp = this.fieldArray[isUUIDpresent].selectArray>
<cfcatch>
<cfreturn "nothing here">
</cfcath>
</cftry>
....rest of code....
But this might be inefficient since I am shifting a lot of data around unnecessarily. Also in my debug I get all these exception calls which I have caught using above method -- they mask a real problem(s) when they arise.
I am open to some nice solution which will solve above problem. Also, it would be a nice change to bring the mailing list away from Eolas patent for a short while :)

Well, I'm not sure Rerun is doing a whole lot of anything now that he's
dead. But the others, maybe. ;)
