Found an end-around. I changed the type of the argument to ANY and it worked.

"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?
