    Wait Modal

    lessonz Newbie

      Okay, I have a h:CommandButton that I want to kick off a process on the server side. At the same time I want it to show a modal. That's working. Once the process on the server side is complete, I want to rerender the modal. That's where I get hung up.


      So basically, I want to launch a wait modal/dialog, letting the user know something is going on. Once that is done, I want to provide that feedback to the user by re-rendering the modal.


      I can't seem to figure out how to do this. Any direction, especially examples, would be greatly appreciated! Thanks.

          Surely someone has had to do similar.

            No idea how to achieve that, but I would also be interested in a possible solution - whereas I would prefer the modal to disappear automatically once the server-process is finished.

              Oliver, thanks for the interest. I would imagine the solution to both of our inquiries would be similar if not the same. Hopefully someone out there can help.

                So, I know this must have something to do with an ajax push, but I'm just not seeing any good documentation on how to do this with RichFaces.

                  I would try to do the following: In some bean, create an accessible attribute which indicates that the process has been finished.


                  <rich:modalPanel id="modal" ....>

                    <h:form id="pollForm">

                      <a4j:poll interval="xxx" enabled="#{not bean.finished}" reRender="modal" />



                    <h:panelGroup rendered="#{not bean.finished} >

                      "please wait" notification


                    <h:panelGroup rendered="#{bean.finished} >

                      content for finished (like button for closing the modalPanel...)


                  <rich:modalPanel ....>

                    You can try this:


                    you must create a status --->

                    <a4j:status name="LoadingStatus" onstart="#{rich:component('Loading')}.show();" onstop="#{rich:component('Loading')}.hide();" />

                    <rich:popupPanel ......>

                         <h:outputLabel value="wait please...">



                    The h:commandButton that you use must replace to a4j:commandButton

                    and in the a4j:commandButton add the attribute status:

                    <a4j:commandButton actionListener or action="#{nameBean.method}" status="LoadingStatus"/>


                    when you pulse the button the popup will open, when the process with the server finish, the popup will close

                      In the end I opted to use onclick="#{rich:component('testPopup')}.show();" and some hide() with two different modals to switch them out when appropriate. It's not ideal, but it seems to work okay.

                        in order to minimize count of code to be added - you could use onsubmit on form. (But in that case panels from a4j:status and onsubmit should be checked to be called once)

                          But that's true, the designed case - calling from a4j:status. But that works for ajax controls only.
