You can also implement mapping like this
=============================================
1. AS VO
----------
Class TestVO
{
public var test1 : String;
public var test2 : Array;
function TestVO ()
{
Object.registerClass ( "testVO", TestVO );
}
}
testVO = new TestVO();
remoteObject.passToCF ( testVO );
=================================================
2. CF
----------
<cffunction name="getASObject" returntype="any" access="remote">
<cfargument name="testVO" type="struct" required="yes">
<cfset var _asVO = arguments.testVO.getType()>
<cfset var _cfVO = CreateObject( "component", _asVO )>
<cfset _cfVO["test1"] = arguments.testVO["test1"]>
<cfset _cfVO["test2"] = arguments.testVO["test2"]>
</cffunction>
<cffunction name="passASObject" returntype="struct" access="remote">
<cfargument name="cfVO" type="TestVO" required="yes">
<cfset var _asVO = CreateObject( "java", "flashgateway.io.ASObject"
).init()>
<cfset _asVO.setType( "testVO" )>
<cfset _asVO["test1"] = arguments.cfVO["test1"]>
<cfset _asVO["test2"] = arguments.cfVO["test2"]>
<cfreturn _asVO>
</cffunction>
===========================================================
3. AS receiving the VO from CF
--------------------------------------
public / private var testVO : TestVO;
testVO = event.result;
==============================================
That should get you going. You might wanna make this mapping a process,
which your service layer invokes before getting Vos into and out of your
backend. You can make it so that you define variables of your CF VO as
properties and loop over the properties to auto populate the AS VO going out
and the same when you read the AS VO. You might also wanna look into Tartan,
which has this mapping built into it and offers seemless integration.
Let me know if you have any questions.
Thanks

I believe the solution Dirk provided solves this problem as well.
That is, in addition to Mehdi's initial solution #2:
> > > remoteObject.cfFunction ( toPass, true );
You can use named argument syntax:
remoteObject.cfFunction({arg1:toPass});
Where arg1 is also the name of the argument in the CFC method "cfFunction".
Mohanraj, this is the solution I posted in my blog:
http://tomlink.net/blog/index.cfm?mode=entry&entry=BBFE84D5-7E97-A3B0-EE0B2D
C292F5272F, where you also posed this question. Please correct me if I am
missing something.
