Sorry, looks like my XML snippet was automatically removed. It was for my task definition. I have 2 user tasks whose id is: userTask1 and userTask2

Hi,

I would add only one note to the answer in stackoverflow.
Have a look on the following jUnit tests in activiti source:


  public void testCompleteWithTaskLocalParameters() {
   ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("testTaskLocalVars");

    // Fetch first task
    Task task = taskService.createTaskQuery().singleResult();

    // Complete first task
    Map<String, Object> taskParams = new HashMap<String, Object>();
    taskParams.put("a", 1);
    taskParams.put("b", 1);
    taskService.complete(task.getId(), taskParams, true);
    
    // Verify vars are not stored process instance wide
    assertNull(runtimeService.getVariable(processInstance.getId(), "a"));
    assertNull(runtimeService.getVariable(processInstance.getId(), "b"));
    
    // verify script listener has done its job
    assertEquals(new Integer(2), runtimeService.getVariable(processInstance.getId(), "sum"));

    // Fetch second task
    taskService.createTaskQuery().singleResult();

  }


  @Deployment(resources = { 
    "org/activiti/engine/test/api/twoTasksProcess.bpmn20.xml" })
  public void testCompleteWithParametersTask() {
    ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("twoTasksProcess");

    // Fetch first task
    Task task = taskService.createTaskQuery().singleResult();
    assertEquals("First task", task.getName());

    // Complete first task
    Map<String, Object> taskParams = new HashMap<String, Object>();
    taskParams.put("myParam", "myValue");
    taskService.complete(task.getId(), taskParams);

    // Fetch second task
    task = taskService.createTaskQuery().singleResult();
    assertEquals("Second task", task.getName());

    // Verify task parameters set on execution
    Map<String, Object> variables = runtimeService.getVariables(processInstance.getId());
    assertEquals(1, variables.size());
    assertEquals("myValue", variables.get("myParam"));
  }

Regards
Martin
