    menuItem - reRender not working

    moldovan Newbie

      Hy Guys!

      It seems to me, that the reRender attribute of the menuItem isn't working. The action-method get called, but the content (is inside t:div), which should be rerenderd, get not updated.

      For testing, i implemented a a4j:button under my dropDownMenu with same action and same id in reRender-attribute. --> with this button it works.

      Also it found this warning in the a4:log, when i click the menuItem

      warn[11:23:26,644]: No information in response about elements to replace

      I'm using jboss-4.0.5GA, myfaces, richfaces+ajax4jsf snapshot from yesterday.

      and for information:
      I cannot surround my content, which should get updated, with an outputPanel and ajaxRendered-attribute setted to true because of complications of the outputpanel and my suggestionbox inside my content.

          Try outputPanel with layout:none - to avoid unnecessary wrapper elements at client side.

            Solved it with a workaround:

            I surrounded the dropdownMenu with an a4j:form and setted the ID's of the content, which should be rerenderd by menuItems in the reRender-attribute of the form.
            This works, and is ok for me, at this time.

              I'm using rich faces 3.0.1 with a rich:toolBar and rich:menuItem ... and I'm facing the same problem.
              The workaround moldovan suggested didn't work for me. I tried surrounding the rich:toolBar with a a4j:form having a reRender attribute in it ... but that didn't work either.

              Does anyone know if that's a bug? Is somebody else facing that problem?

                Hello silenco!

                Try it a 2nd time, it should work. I also have the menu inside a toolbar.

                For help:
                I will post you my main-jsp, and my included menu.jsp (where the menu is located).

                 <h:outputText value="#{applicationUser.userName}" />

                In this way the <t:div id="content"> and it's child-elements get reRenderd correctly

                Hope, this helps!

                  hej moldovan!

                  Thanks a lot for your post. It helped me a lot.
                  The reason why it didn't worked was a missing


                  attribute in the <a4j:form> tag. Otherwise it submits the ajax request, but won't perform any rerendering.

                  Now it's working fine :)

                  Thanks again

                    I had a similar issue with rich:dropDownMenu inside rich:dataTable. When I use ajax submitMode for the rich:menuItem, the action will not be invoked. If I move the dropDownMenu out of rich:dataTable (but in same form), it works as expected.

                    I did some debug tests using firefox firebug. I found the problem was, somehow, the reRender id didn't fill in the Ajax-Update-Ids ().
