I'm having trouble signaling a process instance to advance beyond a wait activity.  I've looked at the jBPM example but no luck.  I have a process definition with numerous state activities.  I created a lisetner for each activity.  The listeners (simulate) some external work then call the executionService.signalExecutionById() method:


    public void notify(EventListenerExecution execution) throws Exception {
        
        System.out.println("MESSAGE: " + msg);
    
        //Timer timer = new Timer();
        //ExternalTaskProxy task = new ExternalTaskProxy();
        //Date now = new Date();
        //timer.schedule(task, now, 1500);
               



        ExecutionService executionService = processEngine.getExecutionService();
        executionService.signalExecutionById(execution.getId());
    }

 
 
I deploy the business archive using an Ant script then run a process instance via the jBPM console.  The process instance starts but halts at the first activity.  Here's the process definition's jpdl code look like this:
 
<?xml version="1.0" encoding="UTF-8"?>

        </on>
      <transition name="to Activity8" to="Activity8" g="-130,-18"/>
   </state>
   <state g="142,846,139,52" name="Activity8">
        <on event="start">
        <event-listener class="my.package.MyListener8"/>
        </on>
      <transition name="to end" to="end" g="-36,-18"/>
   </state>
   <end g="651,849,48,48" name="end"/>
</process>
 
Any help would be appreciated.
