    To realize countersign by jbpm4.3,I get some thing wrong,why?

    li zhi Newbie

      The workflow is:

       

      <?xml version="1.0" encoding="UTF-8"?>

       

      <process name="ComplateTaskTest" xmlns="http://jbpm.org/4/jpdl">
         <start name="start1" g="216,107,48,48">
            <transition name="to task" to="task" g="-35,-17"/>
         </start>
         <task name="task" g="194,215,92,52" assignee="lizhi">
            <transition name="to state1" to="state1" g="-43,-17"/>
            <transition name="to state2" to="state2" g="-43,-17"/>
         </task>
         <state name="state1" g="100,352,92,52"/>
         <state name="state2" g="305,352,92,52"/>
      </process>  

       

      TestUnit:

       

      ProcessEngine processEngine=Configuration.getProcessEngine();
              RepositoryService repositoryService=processEngine.getRepositoryService();
              ExecutionService executionServcice=processEngine.getExecutionService();
              TaskService taskService=processEngine.getTaskService();
              String deployId=repositoryService.createDeployment().addResourceFromClasspath("ComplateTaskTest.jpdl.xml").deploy();
              ProcessInstance pi=executionServcice.startProcessInstanceByKey("ComplateTaskTest");       
              EnvironmentFactory environmentFactory=(EnvironmentFactory) processEngine;
              Environment environment=environmentFactory.openEnvironment();
              DbSession dbSession=environment.get(DbSession.class);
              TaskImpl taskImpl=dbSession.findTaskByExecution(executionServcice.findExecutionById(pi.getId()));
              taskImpl.setSignalling(true);
             
             
              assertEquals("lizhi", taskImpl.getAssignee());
             
              TaskImpl subTask1=taskImpl.createSubTask();
              subTask1.setName("subtask1");
              subTask1.setAssignee("aaa");
              subTask1.setExecution(execution);
              subTask1.setSignalling(false);

       

              dbSession.save(subTask1);
              TaskImpl subTask2=taskImpl.createSubTask();
              subTask2.setName("subtask2");
              subTask2.setAssignee("bbb");
              subTask2.setExecution(execution);
              subTask2.setSignalling(false);

       

              dbSession.save(subTask2);
              dbSession.save(taskImpl);
              List<Task> tasks=taskService.createTaskQuery().processInstanceId(pi.getId()).list();
              assertEquals(1, tasks.size());
              List<Task> subTasks=taskService.getSubTasks(tasks.get(0).getId());
              taskService.completeTask(subTasks.get(0).getId());
              taskService.completeTask(subTasks.get(1).getId());
             
              pi=executionServcice.findProcessInstanceById(pi.getId());
              assertTrue(pi.isActive("task"));
              taskService.completeTask(taskImpl.getId(),"to state1");

       

       

       

      Then i got:
