yes, you can either use web designer or eclipse editor. Some details can be found http://docs.jboss.org/jbpm/v5.4/userguide/ch.human-tasks.html#d0e5078 here.

Hi ,

    I see the "To Users" and "To Groups" is required when i define  a notification of a human task , i mean if just notificate the owners set earlier but not others , can i ignore these two fields or if there is any other alternative solution . 

Thanks.

looks like you don't have UserInfo configured, see this http://mswiderski.blogspot.com/2012/06/self-managable-user-tasks-notification.html post for some hints that might help you out.

Hi Maciej ,


        UserGroupCallbackManager.getInstance().setCallback(userGroupCallback);
        TaskService taskService = new TaskService(emf, SystemEventListenerFactory.getSystemEventListener());
        taskService.setUserinfo(userInfo);

        Both the userGroupCallback and userInfo had beed configured in code .

Look at this initialization https://github.com/droolsjbpm/jbpm/blob/5.4.x/jbpm-human-task/jbpm-human-task-war/src/main/java/org/jbpm/task/servlet/HumanTaskServiceServlet.java#L88 code, you need to set the user info on the escalation handler too. Make sure you use the escalation handler instance when setting up the task service so the proper one will be used.
