Calling HTTP Service from ActionScript

Question

I am trying to move some of my code out of my mxml into seperate action script classes.
Right now I am using the httpservice and simply binding the ResultEvent to a function then can update my ui. Now that I have moved the code out of the UI I don't have the same flexibility.
Consdier the following actionscript.
package services
     import mx.rpc.events.ResultEvent;
     import mx.rpc.http.mxml.HTTPService;
     public class DashBoardService
     public function DashBoardService()
     public function getDashBoard():void{
          var returnData:XML;
          var svc:HTTPService = new HTTPService();
          svc.resultFormat = "e4x";
          svc.showBusyCursor = true;
          svc.method = "GET";
          svc.url="http://localhost/data.xml";
          svc.addEventListener(ResultEvent.RESULT,function(event:ResultEvent):void {
          //do something here
          svc.send();
Ideally I would like to be able to call getDashBoard and have it return non void with the data from the service. Obviously I can't return returnData because it will be null. Any ideas how I can do this? I suppose I can issue an event from the callback and then handle it elsewhere but it seems like overkill for what I need.

Yes. You have to load and call them in the context of an
HTMLLoader object. The usual sandbox considerations apply.
