UIPanelMenu Backingbean not working

[pokito]

I tried to create <rich:panelMenu> from backing-bean, but all functions don't work.

e.g.

1. Expand-button and collaps-button show at the same time

2. I can click expand-button and collaps-button, but it doesn't happen

3. I've disabled the below UIPanelMenuGroup (layout). It shows 2 times righticons

What happens?

What have I done wrong?

.xhtml file

...
<h:panelGrid columns="2" width="300" >
      <rich:panelMenu binding="#{myBean.menu}" />
</h:panelGrid>
...

Managed Bean

private UIPanelMenu menuPanelBinding;

public myBean(){
        initPanelMenu();

FacesContext facesContext = FacesContext.getCurrentInstance();
        Application application = facesContext.getApplication();

        this.menuBinding = (UIPanelMenu) application.createComponent(facesContext, UIPanelMenu.COMPONENT_TYPE, "org.richfaces.PanelMenuRenderer");

public void setMenu(UIPanelMenu menu) {

public UIPanelMenu getMenu() {

}

It works now

At the begining I've create a component without renderer

this.menuBinding = (UIPanelMenu) application.createComponent(UIPanelMenu.COMPONENT_TYPE)

now

this.menuBinding = (UIPanelMenu) application.createComponent(facesContext, UIPanelMenu.COMPONENT_TYPE, "org.richfaces.PanelMenuRenderer");

and then

public void setMenu(UIPanelMenu menu) {
        this.menuBinding = menu;
}

public UIPanelMenu getMenu() {
        initPanelMenu(); // always rerender panelmenu
        return menuBinding;
}

BUT (new problem)

I've set

this.menuBinding.setGroupMode(PanelMenuMode.ajax);
this.menuBinding.setItemMode(PanelMenuMode.ajax);

....

data_item_1.setRender("id_panelMenuGroup2");

When I select for example data_item_1, the listening-content is not changed

Can someone explain how to use .setRender(Object o)?
