我的容器对象的定义：
private static const emptyLink:Object = {
id: -1,title:'',trigger1:'',trigger2:'',trigger3:'',trigger4:'',trigger5:'',linkTitle:'',linkBody:'',answer1:'',answer2:'',answer3:'',answer4:'',answer5:''
};
[Bindable] public var currentLink:Object = emptyLink;
currentLink在运行时被分配到ArrayCollection的特定索引，我主要使用emptyLink对象进行初始化。
<mx:Panel id="triggerPanel" title="Trigger" width="33%">
<mx:VBox id="tpBoxes" width="100%" paddingBottom="5" paddingLeft="5" paddingRight="5" paddingTop="5">
<mx:TextInput id="trigger1" width="100%" textAlign="left" text="{currentLink.trigger1}" />
<mx:TextInput id="trigger2" width="100%" textAlign="left" text="{currentLink.trigger2}" />
<mx:TextInput id="trigger3" width="100%" textAlign="left" text="{currentLink.trigger3}" />
<mx:TextInput id="trigger4" width="100%" textAlign="left" text="{currentLink.trigger4}" />
<mx:TextInput id="trigger5" width="100%" textAlign="left" text="{currentLink.trigger5}" />
</mx:VBox>
</mx:Panel>
当然，这个编译和显示很好，但每个实例都有运行时警告：
warning: unable to bind to property ‘trigger1’ on class ‘Object’ (class is not an IEventdispatcher)
warning: unable to bind to property ‘trigger2’ on class ‘Object’ (class is not an IEventdispatcher)
warning: unable to bind to property ‘trigger3’ on class ‘Object’ (class is not an IEventdispatcher)
warning: unable to bind to property ‘trigger4’ on class ‘Object’ (class is not an IEventdispatcher)
warning: unable to bind to property ‘trigger5’ on class ‘Object’ (class is not an IEventdispatcher)
当TextInput字段更改时，currentLink对象不会更新。
明显的答案是我的对象需要一个实现IEventdispatcher的类的实例。这个答案没有告诉我的是，实现该接口(需要什么，什么不是)的细节，如果有一个更简单的方法来做 – 像一个内置的类，将乐意接受我的自定义属性，并允许对于绑定，没有我不必担心实现接口的细节。
这样的类是否存在？如果没有，完成这项任务的最低和/或接受的标准是什么？
