Flash调试器的行为不同于带有AS3和Events的播放器

var firstParameter:SomeObject = new SomeObject();
someLoader = new Loader();
someLoader.contentLoaderInfo.addEventListener(
    Event.COMPLETE
  , function(evt) {
      onLoaded(evt, firstParameter);
    }
  , false
);

function onLoaded (evt:Event, param:SomeObject):void {
    mcOnSceneForTracing.text = param; // this is used for SWF debugging
}
