Dynamic menu rendering in Richfaces 4

[uipko]

I'm working on the migration of an application from richfaces 3 to richfaces 4.3.3, we use myfaces 2.1.12 and tomcat 6.0.35.

I've the following problem. The buttons on my datascroller aren't working, this seems to be caused by the following error

<partial-response>
  <error>
    <error-name>java.lang.IllegalStateException</error-name>
    <error-message><![CDATA[component with duplicate id "searchForm:j_id_6z" found]]></error-message>
  </error>
</partial-response>

The problem is that we use c:forEach to loop over the menu items. If I understand this correctly c:forEach brakes the partial state rendering. The solution would be to use ui:repeat but this doesn't work to populate menuItems.

The question is how can I dynamicly populate a menu without braking the partial state rendering?

This is a simplified version of the code which generates the problem:

          <rich:dropDownMenu>
            <f:facet name="label">
              <h:panelGroup>
                <h:outputText value="#{msg['menu_dropdown']}" />
              </h:panelGroup>
            </f:facet>
            
            <c:forEach items="#{bean.items}" var="item">
              <rich:menuItem action="#{item.go}" immediate="true">
                #{item.name}" />
              </rich:menuItem>
            </c:forEach>
            
          </rich:dropDownMenu>

Have you tried using a4j:repeat?

Thanks for the quick reply!

I din't try this before, I've tried this now and it also doesn't work. Probably the same issues as with the ui:repeat, rich:menuItem has to be a direct child of rich:dropDownMenu. Do you have any other solutions? The nly thin I can think of is building a custom dropDownMenu.

c:foreach should work provided your list of menu items is static.  You can also file a feature request to have the menuItem work with the a4j:repeat (we recently did this for the toggle components).

c:foreach works for the menu but breaks the partial state rendering which brakes the datascroller on the same page.
