[jboss-user] [JBoss jBPM] - Re: How to retrieve the Task list of a user ?

[dleerob]

In your process definition, you have: 

  | <swimlane name="user">
  | </swimlane>
  | 

You've defined a swimlane called "user", but you haven't assigned any users to that swimlane.

Also, to get a list of tasks that can potentially be assigned to a user, I use a method like this:
/**
  | 	 * Gets all task instances that a user with the given actor id could claim.
  | 	 * @return List of jbpm task instances.
  | 	 */
  | 	public static List getUnClaimedTaskInstancesForActorId (JbpmContext jbpmContext, String actorId) {
  | 		Session session = jbpmContext.getSession();
  | 
  | 		//create list of possible id's (this includes groups) that 
  | 		//belong to the current user.
  | 		List actorsList = new ArrayList();
  | 		actorsList.add(actorId);
  | 		IdentitySession identitySession = new IdentitySession(session);
  | 		org.jbpm.identity.User jbpmUser = identitySession.getUserByName(actorId);
  | 		Iterator i = jbpmUser.getMemberships().iterator(); 
  | 		while(i.hasNext()){ 
  | 			Membership m = (Membership) i.next(); 
  | 			actorsList.add(m.getGroup().getName()); 
  | 		} 
  | 		List pooledTaskInstances = jbpmContext.getTaskMgmtSession().findPooledTaskInstances(actorsList);
  | 		List jbpmTaskInstanceList = session.createQuery("from org.jbpm.taskmgmt.exe.TaskInstance ti where ti.start is null and ti.end is null and actorId = '"+actorId+"'").list();
  | 		//add pooledTaskInstances to taskList
  | 		jbpmTaskInstanceList.addAll(pooledTaskInstances);
  | 
  | 		//TODO sort jbpmTaskInstanceList by task instance id
  | 		
  | 		return jbpmTaskInstanceList;
  | 	}

Hope this helps a bit. Good luck!
