someone can help? Why reRender don´t work with PanelMenu?

[rangelp]

Using richFaces version 3.2.0.GA, when i press F5 to refresh the page it don´t render the PanelMenu in the 3.1.2.SP1 it´s render... it´s a richFaces bug?

Why diferents results with same code (changing only the vesion) ?

In verison 3.1 i put this in the Manage bean to force page refreh:

 FacesContext context = FacesContext.getCurrentInstance();

 Application application = context.getApplication();
 ViewHandler viewHandler = application.getViewHandler();
 UIViewRoot viewRoot = viewHandler.createView(context, context
 .getViewRoot().getViewId());

 context.setViewRoot(viewRoot);
 context.renderResponse();

In version 3.1 this code work´s fine and show me the panelMenu in 3.2 nothing happen.

Someone can help?

Ok, it's a bug the binding doesn't work in 3.2.0GA:

http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4140368#4140368
http://jira.jboss.com/jira/browse/RF-2918

Workarounds
Facelets usage or using RichFaces 3.2.0.SP1 (when released)

Now i'm using facelets and i only see the PanelMenu when i press F5 (refresh).
So reRender doesn't work?

It is not binding or reRender problem. If you used any standard JSF component instead of richfaces components and did not use AJAX, you would have a similar result. Do not create new component instance for binding in action method. For example following code works fine with your example:

 public void criaMenu1(){
...................................
 if (null == menu2) {
 menu2 = new HtmlPanelMenu();
 } else {
 menu2.getChildren().clear();
 }
 menu2.getChildren().add(grupo1);
 menu2.getChildren().add(grupo2);
...................................
 }

Thanks sergeyhalipov. So when I'm using binding i can´t change the reference of the object.

Anyone have some information about this?
