[jboss-user] [JBoss jBPM] - Re: Assign a task to 2 users, how please?

[webjavier]

Yes, the new list display the tasks pending of the group, but when i run a task of one of members of group just execute the task of the user that is logged and after this the another user when loggin don't see his task of the group.
I think this method only assign the task to first user that execute it.
public String assignTaskInstance(){
   	 long id = JsfHelper.getId("taskInstanceId");
   	 TaskInstance taskInst = taskMgmtSession.loadTaskInstance(id);
   	 taskInst.setActorId(userBean.getUserName());
   	 return "home";
     }

PD:Sorry with mi english.....

  | talking about websale example, if you use "group(groupName)" in a task or swimlane assignment, and logging with some of groupName members you will not find any tasks in their tasklist. This is correct because in that tasklist (that of websale example) you will find only task assigned to user logged. If you want to see a tasklist with tasks assigned to user's group, you have to write in home.jsp another list table. See my example below:
