GWT ClickListener或CLlickHandler无法在IE上正常工作

Question

我有一个扩展AbsolutePanel的Panel，每当我添加具有click处理程序的widget时，它都会抛出JS Exception。这仅在IE 8和9中发生。 代码：

  private static class MyCustomPanel extends AbsolutePanel {

  private MyCustomPanel (Element elem) {

     super(elem);
     onAttach();
  }
}

然后我使用这个MyCustomPanel在我的DOM应用程序中添加一些Widgets元素

 final Panel panel = new MyCustomPanel (element);
        panel.add(mywidget); 

 Where mywidget is different widget which implements ClickListner, ClickHandler and so  on.... (In my case I have Scrollable Panel with different Widgets.)
    I get my element with this code: 

   private native static Element getServiceElement(String elementName)
 /*-{
    debugger;
    var element = $wnd.top.document.getElementById("div-"+elementName);

    if (element) {
        element.innerHTML = '';
    }
    return element;
}-*/;
This issue hapens only on IE8 and IE9 on FF and Chrome works fine.

JS Exception

Update!

我发现失败的原因是GWT尝试在我的Element上添加EventEistener，因为某些原因它认为我的浏览器是IE6。有没有办法强制我的面板使用attachEvent而不是addEventListener？
