    a4j:support within a a4j:include (Facelets)

    ter ron Newbie

      Hello,

      I have a a4j:support in a h:selectOneMenu which should update another
      h:selectOneMenu calling a method from a managed-bean manBean.
      This is all located within a, with a4j:include, included page.

      The whole functionality was working before I extracted that part from the main page (parent) to the included page (child). So, without having any a4j:include.

      I read in the doc that you have to reRender the "parent" tag, which in this case is a h:panelGroup:
      ___________Parent Page________________________________
      <h:panelGroup id="theSubpage">
      <a4j:include id="incSub" viewId="../include/SubPage1.xhtml" />
      </h:panelGroup>
      _____________________________________________________

      And I do it this way:

      ___________Child Page________________________________
      <h:panelGroup>
      <h:selectOneMenu id="sel1" rendered="true" value="#manBean.prop1}" styleClass="sc1">
      <f:selectItems value="#{manBean.props1}"/>
      <a4j:support event="onchange" action="#{manBean.action1}" reRender="panelGroup2,theSubpage" />
      </h:selectOneMenu>
      </h:panelGroup>
      _____________________________________________________

      I also reRender panelGroup2, because that contains the selectOneMenu to change.

      Somehow the manBean.action1 is not being called. I see the ajax call coming to the server, but the method is not being call and also no
      error/exception is generated
      ... not even a warning...

      I tried using <a4j:keepAlive beanName="manBean"/> but didn't hep either.

      It all works if I have it in the parent page, but not if I extract it in the child page.

      Any Ideas?
      Thanks!

          you do not have to point to parent component anymore. I was required only for ajax4jsf 1.0.6 (and below) and only if you use a4j:include for navigation. It does not look like your case.

          if you need to use one selectOneMenu to update another, surround the first one with a4j:region

            Hello Sergey + thanks for your answer.

            The question is then why was it working when it was all in one page?

            However, you solution is then to use a4j:region.
            And I have to surround the "master" selectOneMenu ? So, the one firing the changes.

            not the "slave" selectOneMenu (the one being changed by ajax)?

            Thnx!

              the difference between the stuff included with a4j:include and directly located on the page is a prefix of each including id as soon as a4j:include is a naming container from the jsf p+oint of view. ( I do not see why it might be important in your case)

              Recommendation to limit the processing for only the master selectOneMenu is also a general recommendation

                a4j:region is also not helping....


                Why is the method action1 from the a4j:support action, not being called ??!! (action="#{manBean.action1}")


                the event="onchange" is firing an ajax request but the method is not being called...

                  have you used

                  <a4j:outputPanel ajaxRendered="true">
                  <h:messages/>
                  </a4j:outputPanel>
                  

                  inside your form?

                  Colud you please post somewhere your sources to make us shure that we talk about one things..

                  Thanks.

                    yes, I used

                    <a4j:outputPanel ajaxRendered="true">
                    <h:messages/>
                    </a4j:outputPanel>

                    but this is not giving any messages...

                    After trying (more) different things, I used Firefox2. That browser does it! The code is working there as wanted!

                    My problem is that I have to make it for IE6...
                    I compared the two logs (one with FF2 and one with IE6) and they are pretty different.
                    However I have no clue what the issue can be. Maybe you do?
                    I pasted below the log produced after the event="onchange" fired in the a4j:support within the a4j:include.

                      Do you see in the FF2 log that "the method" is being call. That does not happen in the IE6 log.

                      Any idea welcome.
                      thnx

                        I had to give up that idea (something similar to the wizard-demo) of
                        having a progressing small window within a master one,
                        and complete submit the whole page.

                        Is a shame though. It gave it a real rich feeling, but the Ajax functionalities
                        within that small window were not working in IE6 (and that is unfortunately our standard).

                        I have the feeling that that has to do with security configurations... redirection
                        of requests... IE6 is blocking something there. It is a shame that no clear log
                        is being generated (see in this thread earlier posts).
