Navigation Tree event on a link

Hello everybody,

I have a Navigation tree and I want to put an event on a link. How could I do that ?

I have the following code:

..

..

..

private void CreateLink(
			IPortalComponentRequest request,
			TreeNode treeNode,
			INavigationNode node)
		{
			String url = node.getName();
			String title = node.getTitle(request.getLocale());
			Link link = new Link("LINK_" + FirstNodeCount++, title);
			String navigationAction = "EPCM.doNavigate('" + url + "',2)";
			//l.setOnClientClick(navigationAction);
			link.setOnClick("onLink");
			treeNode.setComponent(link);
		}

and

public void onLink(Event event)
		{
			TreeNodeSelectEvent myEvent =  (com.sapportals.htmlb.event.TreeNodeSelectEvent) event;
			TreeNode myNode = navigationBean.getTree();
			System.out.println(myNode.getID());
			TreeNode tempNode = myNode.getNodeByID(myEvent.getNodeKey());
			myNode.setOpen(true);
			navigationBean.setTree(myNode);
		}

Thanks for any feedback

Regards.
