    Seam conversations and third party JSF components libs

    mgrouch Expert

      What is the way to send conversation id with third-party libraries ajax requests. For example, Quipukit library comes with data table
      pagination control which has ajaxed controls. Click on those controls
      submits ajax request without conversation id and causes exception on
      server side

      java.lang.IllegalStateException: No active conversation context
      at org.jboss.seam.core.Conversation.instance(Conversation.java:103)
      at org.jboss.seam.faces.FacesManager.prepareBackswitch(FacesManager.java:236)
      at org.jboss.seam.jsf.SeamPhaseListener.afterRender(SeamPhaseListener.java:505)
      at org.jboss.seam.jsf.SeamPhaseListener.afterServletPhase(SeamPhaseListener.java:230)
      at org.jboss.seam.jsf.SeamPhaseListener.afterPhase(SeamPhaseListener.java:184)


      Is there workaround for it?
      Thanks

          I've made some progress with this issue by adding
          page action

          action="#{myBean.beginCall}"


          <page xmlns="http://jboss.com/products/seam/pages"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://jboss.com/products/seam/pages http://jboss.com/products/seam/pages-2.0.xsd"
           login-required="true"
           conversation-required="false"
           no-conversation-view-id="/home.xhtml"
           action="#{myBean.beginCall}">
           <!--
           <begin-conversation join="true"/>
           -->
          </page>



          and action in myBean

          public String beginCall() {
           Lifecycle.beginCall();
           return null;
           }



          java.lang.IllegalStateException: No active conversation context
          now fixed and disappeared, requests are processed with correct response being rendered. However there are too many exceptions in the log.

          java.lang.IllegalStateException: No phase id bound to current thread
          at org.jboss.seam.contexts.PageContext.getPhaseId(PageContext.java:162)

          Is this even the right approach?
          Thanks

            I've got rid of some exceptions by improving beginCall()

             if (!Contexts.isConversationContextActive()) {
             Lifecycle.beginCall();
             }
             if (!Contexts.isPageContextActive()) {
             FacesLifecycle.resumePage();
             }
             try {
             if (!Transaction.instance().isActiveOrMarkedRollback()) {
             Transaction.instance().begin();
             }
             }
             catch (Exception ex) {
             throw new IllegalStateException("Could not start transaction", ex);
             }


            I still have this exception which I haven't figured out how to get rid of:

              Take a look org.jboss.seam.ui.resource.StyleResource.getResource() for how to properly run your code inside the Seam lifecycle.

                Hmm. Looking at that doesn't help me (or I do not undersand something).
                I think now I can explain my problem better.

                When quipukit submits its own ajax requests (like during the click on pagination control) all Seam contexts are not available on server side.
                What would be a workaround to fix it? I do not have the source of quipukit
                as it is proprietary and it works with Seam 1.2.1.GA. The problem is only with Seam 2.0.Beta1.

                Thanks
