flex与java通信 实现动态birdeye

大家好，我是个javaer，现在项目需求有个flex拓补图，我用的是birdeye.查找了半天，找到了相关源码

protected function nodeDoubleClick(e:MouseEvent):void {
			var comp:UIComponent;
			var vnode:IVisualNode;
			
			/* get the view object that was klicked on (actually
			* the one that has the event handler registered, which
			* is the VNode's view */
			comp = (e.currentTarget as UIComponent);
			
			/* get the associated VNode */
			vnode = lookupNode(comp);
			currentNodeId = vnode.node.id;
			//Alert.show(currentNodeId.toString(),"提示");
			var evt:VisualNodeEvent = new VisualNodeEvent(VisualNodeEvent.DOUBLE_CLICK, vnode.node,e.ctrlKey);
			dispatchEvent(evt);
			//LogUtil.debug(_LOG, "double click!");
			
			/* Now we change the root node, we go through
			* our public setter method to get all associated
			* updates done. */
			this.currentRootVNode = vnode;
			//Alert.show("测试双击1","提示");
			//trace("测试双击");
			//LogUtil.debug(_LOG, "currentVNode:"+this.currentRootVNode.id);
			
			/* here we still want to implicitly redraw */
			draw();
		}

这是节点双击事件，其中分发了visualnode双击事件

var evt:VisualNodeEvent = new VisualNodeEvent(VisualNodeEvent.DOUBLE_CLICK, vnode.node,e.ctrlKey);
			dispatchEvent(evt);

以上birdeye源码到里应该很清楚怎么做了
我在传入所需xml字符串里的节点增加监听命令，然后添加方法

"<Node id=\"1\" name=\"wwww\" nodeDoubleClick=\"testdouble(event)\" nodeColor=\"0xaf3a99\" nodeSize=\"30\" nodeIcon=\"center\" />"

protected function testdouble(event:VisualNodeEvent):void
			{
                             //将节点id传给java然后再组成新的xml字符串传给flex，应该就可以实现了动态的birdeye
				Alert.show(event.node.id.toString(),"rjfi");
				
			}

问题是testdouble没有响应，没有alert,为什么？请flex兄弟给小弟解答一下，十分感谢！

你的意思是不是双击事件没有相应？

我是按他的例子来做的vgraph.addEventListener(VGNodeEvent.VG_NODE_DOUBLE_CLICK, XXX);
