Hi All,
Just to follow up on this - now that I am back to working on this issue...
And, not that I ever doubted Charlie... but a some working code is worth a
thousand words...
<cffunction name="blah">
<cfargument name="messageid" required="false" />
<cfargument name="text" required="false" />
<cfargument name="queryid" required="false" />
<cfargument name="datasource" required="false" />
<cfset var local = {} >
<cfset local.mystruct.1 = arrayIsDefined(arguments, 1)>
<cfset local.mystruct.2 = arrayIsDefined(arguments, 2)>
<cfset local.mystruct.3 = arrayIsDefined(arguments, 3)>
<cfset local.mystruct.4 = arrayIsDefined(arguments, 4)>
<cfreturn local.mystruct>
</cffunction><cfset myStruct = blah(text="gav", queryid=3)>
<cfdump var="#myStruct#">
Gives the following;
struct 1 NO 2 YES 3 YES 4 NO
Which will solve the issue I am having, thanks Charlie.
Though I still think the implementation should be consistent across all
functions.
Gavin.
