actionscript-3 – Flash事件执行顺序

package
{
    import flash.display.Sprite;
    import flash.events.Event;

    public class TestFlashEvents extends Sprite
    {
        private static const DUMMY_EVENT:String = "DummyEvent";
        private var dummyObjects:Vector.<DummyObject> = new Vector.<DummyObject>(100);
        public function TestFlashEvents()
        {
            for(var i:int = 0; i < dummyObjects.length; i++){
                dummyObjects[i] = new DummyObject(this);
                addEventListener(DUMMY_EVENT,dummyObjects[i].listener);
            }
            removeEventListener(DUMMY_EVENT,dummyObjects[41].listener);
            dispatchEvent(new Event(DUMMY_EVENT));
        }

        private var counter:int = 0;
        public function onGettingEvent(dummyObject:DummyObject):void{
            if(counter == 25){
                for(var i:int = 0; i < 50; i++){
                    removeEventListener(DUMMY_EVENT,dummyObjects[i].listener);
                    trace("Removing",dummyObjects[i].id);
                }
            }
            trace("Handeling event",counter,dummyObject.id);
            counter++;
        }
    }
}
import flash.events.Event;

class DummyObject
{
    private static var dummyObjectsCounter:int = 0;

    public var id:String;
    private var tester:TestFlashEvents;

    public function DummyObject(tester:TestFlashEvents)
    {
        this.tester = tester;
        id = "DummyObject " + dummyObjectsCounter;
        dummyObjectsCounter++;
    }

    public function listener(event:Event):void{
        tester.onGettingEvent(this);
    }
}

removeEventListener函数实际上不起作用.告诉我你怎么看待它.我还在adobe中打开了一个错误.
