Hi,

I've just started using Richfaces. My first JSF application. I'm combining this with Facelets and JSF 1.2.

I've buid panelMenu in this style:
<rich:panelMenu binding="#{leftMenu.panelMenu}" mode="ajax"/>

With a LeftMenu class looking something like this:

 private HtmlPanelMenu panelMenu;
...
 public HtmlPanelMenu getPanelMenu() {
 if (this.panelMenu == null) {
 this.panelMenu = new HtmlPanelMenu();
 this.fillMenu(this.panelMenu);
 }
 return this.panelMenu;
 }
....

This worked good.

Until I tried to add an actionListeren or ajaxListener:

(inside the fillMenu() method..)

panelMenuItem.addActionListener(new ActionListener() {
 public void processAction(final ActionEvent event) {
 System.out.println("processing");
 }});
..

From the moment that this (or the addAjaxListener equivalent is added I constantly have the following exception:

So... please help me... I don't really understand this exception and can't detect any other exceptions. Considering it works withouth adding a listener, this must be very specific. In the end I just want the same behaviour as the panelMenu on the demo application, except that the menuitems are retrieved from backend.

Thanks for any help
