--------------------------------------------------------------
The workflow is:

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

<process name="ComplateTaskTest" xmlns=" http://jbpm.org/4/jpdl 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:
