CFINVOKE

[weblover]

Hi,

I've a problem invoking 2 cfc's in one function which has same return
variable. please see the below code. my question is how does it affect if i
return one variable for cfreturn variable. or how do i return 2 diff.variables
for one function, is it possible.

================================================== =======================

<cffunction name="test" access="remote" output="true" returnType="struct">
<cfargument name="testFields" type="struct">

<cfinvoke component="testOne"
method="TestOne"
returnVariable="ReturnValue">
<cfinvokeargument name="tFields" value="#tFields#">
</cfinvoke>

<cfinvoke component="testOne"
method="testtwo"
returnVariable="ReturnValue">
<cfinvokeargument name="tFields" value="#tFields#">
</cfinvoke>

<cfreturn ReturnValue>

</cffunction>

================================================== ==============================
=============

appreciate if anybody could help me.
thanks,

This function will return the result from the testtwo method only, as it is called second it overwrites the ReturnValue variable set by the TestOne method.

To return multiple values from a function add them to a structure.

[weblover]

does it look like this. pls.advise.

<cffunction name="test" access="remote" output="true" returnType="struct">
<cfargument name="testFields" type="struct">

<cfset treturnvalue = StructNew()>

<cfinvoke component="testOne"
method="TestOne"
returnVariable="treturnvalue.ReturnValue(1)">
<cfinvokeargument name="tFields" value="#tFields#">
</cfinvoke>

<cfinvoke component="testOne"
method="testtwo"
returnVariable="treturnvalue.ReturnValue(2)">
<cfinvokeargument name="tFields" value="#tFields#">
</cfinvoke>

<cfreturn ReturnValue>

</cffunction>

I'd use one of the examples below. No need to invoke the same object twice w/i
the same function call. Also, if you're just using numeric keys, you don't
need a 'Struct'. Use an array.



<!--- Option 1 --->
<cffunction name="test" access="remote" output="true" returnType="struct">
<cfargument name="testFields" type="struct">
<cfscript>
var objTest = createObject("component", "testOne");
var treturnvalue = StructNew();
treturnvalue[1] = objTest.testOne(arguments.tFields);;
treturnvalue[2] = objTest.testTwo(arguments.tFields);

return treturnvalue;
</cfscript>
</cffunction>

<!--- Option 2 --->
<cffunction name="test" access="remote" output="true" returnType="struct">
<cfargument name="testFields" type="struct">
<cfset var treturnvalue = StructNew()>
<cfset var objTest = "">
<cfobject component="testOne" name="objTest" />
<cfset treturnvalue[1] = objTest.testOne(arguments.tFields)>
<cfset treturnvalue[2] = objTest.testTwo(arguments.tFields)>
<cfreturn treturnvalue>
</cffunction>
