Guten Morgen Holger,

hier ist mal eine Version, die den originalen Broadcast benutzt,
und bei der man während des Broadcasts löschen kann.
Dazu wird vor dem Broadcast einfach die ListenerListe
kopiert und die Funktionen umgebogen, die die ListenerListe
verändern.

<code>
function TurboBroadcaster(){
}

o = TurboBroadcaster;

o.broadcastMessage = function(){
 this._saveListeners = this._listeners;
 this._listeners = this._listeners.slice(0);
 //
 this.removeListener = this.removeListenerWhileBroadcasting;
 this.addListener = this.addListenerWhileBroadcasting;
 //
 this.orgBroadcastMessage.apply(this, arguments);
 //
 this._listeners = this._saveListeners;
 //
 this.removeListener = this.orgRemoveListener;
 this.addListener = this.orgAddListener;
}

o.removeListenerWhileBroadcasting = function(obj){
 var tmpListeners = this._listeners;
 this._listeners = this._saveListeners;
 var result = this.orgRemoveListener(obj);
 this._listeners = tmpListeners;
 return result;
}

o.addListenerWhileBroadcasting = function(obj){
 var tmpListeners = this._listeners;
 this._listeners = this._saveListeners;
 var result = this.orgAddListener(obj);
 this._listeners = tmpListeners;
 return result;
}

o.initialize = function(obj){
 ASBroadcaster.initialize(obj);
 obj.orgRemoveListener = obj.removeListener;
 obj.orgAddListener = obj.addListener;
 obj.orgBroadcastMessage = obj.broadcastMessage;
 //
 obj.broadcastMessage = this.broadcastMessage;
 obj.removeListenerWhileBroadcasting = this.removeListenerWhileBroadcasting
 obj.addListenerWhileBroadcasting = this.addListenerWhileBroadcasting;
}

Welt = function (pIntKaefer) {
 TurboBroadcaster.initialize(this);
 ASSetPropFlags(this, null, 0, 1);
 for(var i in this) trace(i);
 //
 while (pIntKaefer--)
  new Kaefer(this, pIntKaefer);
}

Welt.prototype.armageddon = function () {
 this.broadcastMessage('onArmageddon');
}

Kaefer = function (pObjWelt, pIntId) {
 this.intId = pIntId;
 this.objWelt = pObjWelt;
 this.objWelt.addListener(this);
}

Kaefer.prototype.onArmageddon = function () {
 trace(this.intId + ' hat das zeitliche gesegnet');
 this.objWelt.removeListener(this);
}

objWelt = new Welt(10);
objWelt.armageddon();
</code>
