Hello, I need a little help with Task List.
I have a Servlet which I use as front-end for a JBPM process.

Here's one simple:

<?xml version="1.0" encoding="UTF-8"?>
  | <process-definition 
  |   xmlns="urn:jbpm.org:jpdl-3.2"
  |   name="simple3">
  |    <start-state name="StatoIniz">
  |       <transition name="" to="state1"></transition>
  |    </start-state>
  |    <state name="state1">
  |       <transition name="" to="state2"></transition>
  |    </state>
  |    <state name="state2">
  |       <transition name="" to="Task1"></transition>
  |    </state>
  |    <task-node name="Task1">
  |       <task name="Task1">
  |         <assignment class='com.sample.action.SimpleAssignmentHandler' />
  |       </task>
  |       <transition name="" to="end1"></transition>
  |    </task-node>
  |    <end-state name="end1"></end-state>
  | </process-definition>

I want that when the user reaches "Task1" process stops and the Servlet prints "User you have Task1 in charge".

I'm using "getTaskList" for this purpose....

List taskInstances = jbpmContext.getTaskList("user");
  | 	        TaskInstance taskInstance = (TaskInstance) taskInstances.get(0);
  | 	        taskInstanceId = taskInstance.getId();
  | 	        String taskName = taskInstance.getTask().getName();
  | 	         out.println("You have in your TaskList "+taskName);

The problem is getTaskList() returns the taskInstance Task1 also when the user is in state1 or state2. Why ?

I only want this when the process has stopped and waiting for Task completion.

Should I use a different Api for this purpose ?
Thanks a lot
