Christian Küppers commented on RF-2922:
---------------------------------------

Since value attribute is deprecated, the ValueExpression for expanded should have the key "value" in bindings and not "expanded".

org.richfaces.taglib.PanelMenuGroupTagBase:
       protected void setProperties(UIComponent component) {
                super.setProperties(component);
		
               UIPanelMenuGroup panelMenu = (UIPanelMenuGroup) component;
		
               if (_value != null) {
                        if (_value.isLiteralText()) {
                                try {
                                        panelMenu.setExpanded(Boolean.parseBoolean(_value.getExpressionString()));
                                } catch (ELException e) {
                                        throw new FacesException(e);
                                }
                        } else {
                                component.setValueExpression("expanded", _value);
                        }
                }else{
                        panelMenu.setExpanded(false);	
                }	
          }


Because the method isExpanded in UIPanelMenuGroup looks for the binding "value".
