Solved. Created the timer within an ActionHandler:

First define an event on the state:


  | 	public void createTimer(State myState){
  | 		Delegation delegate=new Delegation("com.jotatech.vgrc.action.visual.MyActionHandler");
  | 		
  | 		Event myEvent=new Event(Event.EVENTTYPE_NODE_ENTER);
  | 		
  | 		Action myAction=new Action(delegate);
  | 		myAction.setName("[ACTION]");
  | 		
  | 		myEvent.addAction(myAction);
  | 				
  | 		myState.setAction(myAction);
  | 		myState.addEvent(myEvent);
  | 	}
  | 

Then in the ActionHandler:


  | public class MyActionHandler implements ActionHandler{
  | 	
  | 	private static final long serialVersionUID = -7574831777028763706L;
  | 
  | 	public void execute(ExecutionContext context) throws Exception{
  | 		
  | 		if(context.getTimer()==null){
  | 			System.out.println("ADDING TIMER ...");
  | 			Calendar cal=Calendar.getInstance();
  | 			BusinessCalendar bc=new BusinessCalendar();
  | 			Duration duration=new Duration("20 seconds");
  | 			Date dueDate=bc.add(cal.getTime(), duration);
  | 			
  | 			Timer myTimer=new Timer();
  | 			myTimer.setName("[TIMER] "+context.getEventSource().getName());
  | 			myTimer.setDueDate(dueDate);
  | 			myTimer.setRepeat("20 seconds");
  | 			myTimer.setRetries(3);
  | 			
  | 			myTimer.setAction(context.getAction());
  | 			
  | 			context.setTimer(myTimer);
  | 			
  | 			context.getJbpmContext().getServices().getSchedulerService().createTimer(myTimer);
  | 		}else{
  | 			System.out.println("EXECUTING ...");
  | 			/* CODE YOU WANT THE TIMER TO EXECUTE */
  | 		}
  | 	}
  | 

Hope this helps anybody with the same problem. Question: how can I inject a SEAM component or a Stateful session bean in the timer? I mean: I can't do Component.getInstance("SEAMComponent") or Component.getInstance("MySFSB"). Maybe a way to merge both SEAM and JBPM Contexts? Thanks in advance.
