org.activiti.engine.task.IdentityLink
An identity link is used to associate a task with a certain identity. For example: - a user can be an assignee (= identity link type) for a task - a group can be a candidate-group (= identity link type) for a task @author Joram Barrez

      List<IdentityLink> identityLinks = taskService.getIdentityLinksForTask(task.getId());
      Iterator<IdentityLink> identityLinkIterator = identityLinks.iterator();
        
      boolean pageFound = false;
      while (!pageFound && identityLinkIterator.hasNext()) {
        IdentityLink identityLink = identityLinkIterator.next();
        if (identityLink.getGroupId() != null && groupIds.contains(identityLink.getGroupId())) {
          showQueuedPage(identityLink.getGroupId(), task.getId());
          pageFound = true;
        }
      }
      
      // We've tried hard enough, the user now gets a notification. He deserves it.
