为什么我为实现的IEventDispatcher接口获取“未定义的方法”？

Question

我有一个奇怪的情况，我不明白为什么，我已经实现了IEventDispatcher接口没有编制，我越来越Error: Call to a possibly undefined method addEventListener和Error: Call to a possibly undefined method removeEventListener.

有一个很好的机会，我做的事情令人难以置信的愚蠢在这里，我只是不知道它是什么...

以下是那些在setTransformListner的身体和“removeTransformListener”抛出这些错误（意为“查看”工作方法的类中的方法：

public function setTransformListener(view:AbstractView):void 
{ 
    view.addEventListener(CustomEvent.TRANSFORM, transform); 
} 

public function removeTransformListener(view:AbstractView):void 
{ 
    view.removeEventListener(CustomEvent.TRANSFORM, transform); 
} 

private function transform(e:CustomEvent):void 
{ 

} 

这里是事件D ispatcher类...

package view 
{ 
    import flash.events.Event; 
    import flash.events.EventDispatcher; 
    import flash.events.IEventDispatcher; 

    public class AbstractView implements IEventDispatcher 
    { 

     private var _dispatcher:EventDispatcher; 

     public function AbstractView():void 
     { 
      _dispatcher = new EventDispatcher(this); 
     } 

     /* INTERFACE flash.events.IEventDispatcher */ 

     public function addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void 
     { 
      _dispatcher.addEventListener(type, listener, useCapture, priority, useWeakReference); 
     } 

     public function dispatchEvent(evt:Event):Boolean 
     { 
      return _dispatcher.dispatchEvent(evt); 
     } 

     public function hasEventListener(type:String):Boolean 
     { 
      return _dispatcher.hasEventListener(type); 
     } 

     public function removeEventListener(type:String, listener:Function, useCapture:Boolean = false):void 
     { 
      _dispatcher.removeEventListener(type, listener, useCapture); 
     } 

     public function willTrigger(type:String):Boolean 
     { 
      return _dispatcher.willTrigger(type); 
     } 

    } 

}

胡乱猜测，你包的名字是view和你想打电话view.addEventListener，请尝试更改包名。尽管应该先使用本地变量view。
