Problem with reRender and PanelMenuItem

raible1 Sep 10, 2007 2:16 PM

Hello,

I use the RC5 and MyFaces 1.1.5. The view is assembled directly by Java Code:

HtmlPanelMenuItem menuItem = new HtmlPanelMenuItem();
menuItem.setMode("ajax");
menuItem.getAttributes().put("reRender", "form:panel");
menuItem.setLabel("Auftrag");
menuItem.setAction(createMethodBinding());
menu.getChildren().add(menuItem);

My page contains a PanelMenu and as direct childs PanelMenuItems, the mode is "ajax". The request is sent to the server, but the reRender does not work.

Is there a problem with the RC5 or with my approach ?

Thanks for your help.

regards,
Oliver

I tried the whole thing in the meantime, with commandbuttons as childs of the menuitems (menuitem::mode="none"). Same reRender-Id. This works.

You don't set id attribute for a menu component. For a null id values, JSF generate different results on every call to the getClientId method. try to change your code :
HtmlPanelMenuItem menuItem = new HtmlPanelMenuItem(); menuItem.setId("myItem"); menuItem.setMode("ajax"); ....

Done. id is now set to menuitem and menu, but still the same problem.

As I mentioned earlier, a commandbutton as child of the menuitem works. So it seems nothing wrong with the reRenderId itself.
