Warum kann ich auf die _listener nicht zugreifen

[TigerFox]

PHP-Code:

obj = {};
obj.name = "listener1";
obj.onKlick = function() {
    trace("hallo");
};
ASBroadcaster.initialize(mc);
mc.addListener(obj);
mc.onPress = function() {
    this.broadcastMessage("onKlick");
trace(this._listener);
};
ASSetPropFlags(mc, null, 8, 1); 


sind doch hier, wie man sieht!

Level #0:
Variable _level0.$version = "WIN 6,0,21,0"
Variable _level0.obj = [object #1, class 'Object'] {
    name:"listener1",
    onKlick:[function 'onKlick']
  }
Movie Clip: Target="_level0.mc"
Variable _level0.mc.constructor = [function 'MovieClip']
Variable _level0.mc.__proto__ = [object #4, class 'Object'] {}
Variable _level0.mc.broadcastMessage = [function 'broadcastMessage']
Variable _level0.mc.addListener = [function 'addListener']
Variable _level0.mc.removeListener = [function 'removeListener']
Variable _level0.mc._listeners = [object #8, class 'Array'] [
    0:[object #1, class 'Object']
  ]
Variable _level0.mc.onPress = [function 'onPress']

sind doch hier

gibt trace(this._listener) nen undefined aus?

trace(this._listeners);
