    Conversation...problems with it

    Anton Anton Newbie
      Hi everyone.

      I have some application, built with Seam framework. Its have one process-definition, on which users go through 4 pages. I.e. there are 4 <task-node>'s, each contain one <task>. Work is happening so - the user starts the process by clicking button, falls at first <task-node>(first page), then click h:commandLink, on which method with @BeginTask and @EndTask(transition="next") is executed and after that he falls at second <task-node>.
      And now my question :)
      I need that all 4 pages were in one conversation object. Ie in creation of the process, conversation was created (for this I am to the button, which creates a process, writing <s:conversationPropagation type="join" />) and then on page 4 stopped. But the problem is, that when on first page user click on h:commandLink and method with @BeginTask and @EndTask(transition="next") is executed, i see this exception :

      javax.ejb.EJBTransactionRolledbackException: begin method invoked from a long-running conversation, try using @Begin(join=true) on method: finishTaskAndContinue
      javax.faces.el.EvaluationException: javax.ejb.EJBTransactionRolledbackException: begin method invoked from a long-running conversation, try using @Begin(join=true) on method: finishTaskAndContinue
