[flexcoders] rss feed not working

[hworke]

  Hi am reading an rss file and calling the HTTPService with
  action script then handling the HTTPService result to a 
  AsyncToken and finally handling the result is onResult function.

  But for some reason It is not giving me any return.
  Here is the HTTPService and the function that calls it:

    <mx:HTTPService id="httpRSS" url="{ rssURL }"   
        resultFormat="object" showBusyCursor="true"/>


     public function init():void
     {
        httpRSS.send();
        var token:AsyncToken = httpRSS.send();
        var callResponder:Responder = new Responder(onResult,onFault); 
     }
            
     public function onResult(event:ResultEvent):void
     {
        var tmp:Object = event.result.RDF.item;
        var items:Array = new Array();
        for( var i:String in tmp )
        {
          items.push( tmp[i] );
        }
        externalData = new ArrayCollection( items );                    
     }
