How to get webservice result as "e4x" format in a professional solution?

Question

Hi. I want to get data from a .Net webservice as "e4x"
format. It works when i use <mx notation to define the service
in flex. However i want to build a more professional solution and
want to implement the webservice as a class. But I can't get it to
work such that i return the result as "e4x". Instead i get an
object with arrays etc. The problems might be that i need to use
the flex class operation to define "e4x" and then i need to bind
the operation with the webservice but it seems that the webservice
still doesn't know about to return the result as e4x. Here you see
the code in <mx notation which is working fine:
<mx:WebService id="WS" wsdl="
http://localhost/testservice/service.asmx?WSDL"
result="WS_onResult(event)" >
<mx:operation name="HelloWorld" resultFormat="e4x" >
<mx:request></mx:request>
</mx:operation>
</mx:WebService>
And in the WS_onResult procedure i get the result by doing
this:
var xmlResult:XML = XML(event.result);
As i said the above code is working fine but the code below
doesn't work well because it doesn't return the result as "e4x":
WS = new mx.rpc.soap.WebService();
WS.wsdl = "
http://localhost/testservice/service.asmx?WSDL";
WS.addEventListener(LoadEvent.LOAD, load_listener);
WS.addEventListener(ResultEvent.RESULT, result_listener);
OP = new mx.rpc.soap.Operation(WS,"HelloWorld");
WS.loadWSDL();
And in the load procedure to perform the call:
public function load_listener(event:LoadEvent):void {
OP.resultFormat = "e4x";
WS.HelloWorld.send();
And in the result listener i get a result as object and NOT
as "e4x". Can anyone help?
Btw. here i add the .Net code:
[WebMethod]
public XmlElement HelloWorld() {
XmlDocument doc = new XmlDocument();
string xml = "<Test>this is a test</Test>";
doc.LoadXml(xml);
return doc.DocumentElement;
}

Hmm, try setting the resultFormat at the WS level. But what
you have looks like it should work.
