Can cfmodule return values to caller's local scope?

Question

Inside the cfm of the cfmodule, values are returned through the use of Caller scope. If I call a cfmodule inside a function in a CFC, Caller maps to the Variables scope of

Answer 1

Yes, to all of the above. A demonstration:

Testing.cfc:

<cfcomponent>

    <cfset Variables.Instance = {} />

    <cffunction name="checkTheScopeYo" returntype="Struct">

        <cfset var LOCAL = {} />

        <!--- Call a CFModule --->
        <cfmodule template="TestModule.cfm" />

        <cfset Variables.theLocal = LOCAL />

        <cfreturn Variables />

    </cffunction>
</cfcomponent>

TestModule.cfm:

<cfif thisTag.ExecutionMode EQ "end">

    <cfset Caller.FromModule = "Set to the Variables scope" />

    <cfset Caller.Instance.FromModule = "Set to the Variables.instance variable" />

    <cfset Caller.Local.FromModule = "Set to the LOCAL scope" />

</cfif>

Scribble.cfm:

<cfset theResult = CreateObject("component", "Testing").checkTheScopeYo() />

<cfdump var="#theResult#">

The dump shows you that you have access to the local variables within the function, as well as the variables scope of the entire CFC:
