Guys,

I have a process with 2 tasks. I am using local task service. The process starts fine and completion of 1st task is also clean. but the 2nd task is not assigned. neither it is listed in the database. What could be the reason?

Following is my code for initiate process and complete task.

Initiate :

StatefulKnowledgeSession ksession;
  long processInstanceId = -1;
  try
  {
   ksession = BpmRepositoryConfig.createSession(processName);
   KnowledgeRuntimeLogger logger1 = KnowledgeRuntimeLoggerFactory.newThreadedFileLogger(ksession, "testlog", 1000);
   LocalHTWorkItemHandler handler = new LocalHTWorkItemHandler(ksession);
   org.jbpm.task.service.TaskService service = BpmRepositoryConfig.getService();
   TaskService taService = BpmRepositoryConfig.getTaskService(ksession, service);
   handler.setClient(taService);
   ksession.getWorkItemManager().registerWorkItemHandler("Human Task", handler);
      JPAWorkingMemoryDbLogger logger2 = new JPAWorkingMemoryDbLogger(ksession);
        ProcessInstance prcInstance = ksession.startProcess(processDefId, mapParameters);
        processInstanceId = prcInstance.getId();
  }
  catch (Exception e)
  {
   e.printStackTrace();
  }
 


Complete :

StatefulKnowledgeSession ksession = BpmRepositoryConfig.createSession(processName);
  org.jbpm.task.service.TaskService tservice = BpmRepositoryConfig.getService(); 
  TaskService taskService = BpmRepositoryConfig.getTaskService(ksession,tservice);
  try
  {
   for(long task : taskId)
   {
    taskService.start(task, userId); 
    taskService.complete(task, userId, null);
   }
  }
  catch (Exception e)
  {
   e.printStackTrace();
  }
 


Other methods : 


 public static org.jbpm.task.service.TaskService getService()
 {
  EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.jbpm.task");
  org.jbpm.task.service.TaskService tservice = new org.jbpm.task.service.TaskService(emf, SystemEventListenerFactory.getSystemEventListener());
  TaskServiceSession taskSession = tservice.createSession();   
        taskSession.addUser(new User("Administrator"));
        taskSession.addUser(new User("krisv")); 
        taskSession.addUser(new User("john"));
        taskSession.addUser(new User("mary"));
  return tservice;
 }
 
 
 public static  TaskService getTaskService(StatefulKnowledgeSession ksession,org.jbpm.task.service.TaskService taskService)
 {       
  TaskService client = new LocalTaskService(taskService);
        LocalHTWorkItemHandler localHTWorkItemHandler = new LocalHTWorkItemHandler(client, ksession);
     ksession.getWorkItemManager().registerWorkItemHandler("Human Task", localHTWorkItemHandler);
     return client;  
    }
 



Thanks.
