    Continue process Instance

    marcosdutto Newbie


      I have a simple process with 3 User Tasks. I am trying to load the session and continue with the process but it doesn't work.

      When i complete a task from a process created in the same execution of the program it works. But when I complete a User task from a process saved previously it doesn't work. I think that the task is completed but jbpm doesn't know where it has to continue or something like that.


      Doing a test i use the lines:

                processInstance2 =  (RuleFlowProcessInstance) ksession.getProcessInstance(XX);

                NodeInstance nodeInstance = processInstance2.getNodeInstance();


      and the node Instance is always an instance from the first User Task. Moreover, being at the second Task of my processInstance i saved the session after that i loaded that session and the same thing happened (the node Instance was an instance from the first User Task).


      This is my piece of code:


      public static final void main(String[] args) throws Exception {        
              KnowledgeBase kbase = readKnowledgeBase();
              EntityManagerFactory emf = Persistence.createEntityManagerFactory( "org.jbpm.persistence.jpa" );
              Environment env = KnowledgeBaseFactory.newEnvironment();
              env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);
              StatefulKnowledgeSession ksession = JPAKnowledgeService.loadStatefulKnowledgeSession(2, kbase, null, env );
              ksession.getWorkItemManager().registerWorkItemHandler("Human Task", new CommandBasedWSHumanTaskHandler(ksession));
              JPAWorkingMemoryDbLogger dblogger = new JPAWorkingMemoryDbLogger(ksession);
              Map<String, Object> params = new HashMap<String, Object>();
              ksession.addEventListener(new GecosProcessListener());
              ksession.signalEvent("Trigger", null);
              RuleFlowProcessInstance processInstance =  (RuleFlowProcessInstance) ksession.startProcess("simple",params);
              System.out.println("Id session: "+ksession.getId());
              System.out.println("Process Instances: "+ksession.getProcessInstances().size());
              System.out.println("Process Instance ID: "+processInstance.getId());
