when i try to trace this object:

----
public class FeedLoader extends EventDispatcher
{
public var result:String;
public function FeedLoader(url:String)
{
(new MonsterDebugger(this))
var ldr:URLLoader = new URLLoader(new URLRequest(url));
ldr.addEventListener(Event.COMPLETE, dale);
}

private function dale(e:Event):void
{
result = e.target.data;
dispatchEvent(e);
MonsterDebugger.trace(this, this, 0xff0000, true);
}
