Object A extends object B
Method B.collectFields()
-------------------------
<cfif isDefined("URL")>
<cfloop collection="#URL#" item="key">
<cfif isDefined("this." & key)>
<cfinvoke component="#this#" method="#key#"
newvalue="#url[key]#">
</cfif>
</cfloop>
</cfif>
When I call A.collectFields() the isDefined function returns true, but the
CFINVOKE tag throws...
"The system has attempted to use an undefined value, which usually indicates
a programming error, either in your code or some system code.
Null Pointers are another name for undefined values."
---------------------------------------------------------------------
<cffunction name="section_id" returntype="numeric" output="false">
<cfargument name="newvalue" type="numeric" required="false">
<cfif isDefined("arguments.newvalue")>
<cfset variables.section_id = arguments.newvalue>
<cfelse>
<cfreturn variables.section_id>
</cfif>
</cffunction>
---------------------------------------------------------------------
Here's the kicker, if I change the name of the attribute in the CFINVOKE tag
to something else, for example:
<cfinvoke component="#this#" method="#key#" attrval="#url[key]#">
The error no longer is thrown. It's only when the attribute's name actually
matches that of the argument in the method that I see the error. Am I
trying to do something I shouldn't?
Thanks,
Steve
