Well here is how I handle it in my app. Certainly not a fool proof solution,
but should get you pretty close.
When a process enters a task node, I have a swimlane setup with an assignment
handler. That assignment handler queries the database and selects a group of
users that could work this task and does a group assignment to the task.
Then the user sits at their workstation and sees a lists of tasks that they
could work...
jbpmContext.getGroupTaskList("tasomeone");
They would then click on a task to work. When they do I assign the task to
them and open the form that they will use to complete the task. I hoping they
will live the 1min (and much longer in most cases) it takes to complete the
task .
taskInstance.start(actorId);
Assuming they live long enough to complete the task everything should be fine.
Now I understand that like myself through years of drinking, smoking and other
activities that I will not mention to keep it PG-13, the users may not be a
picture of health. In that case you can call this method on the taskInstance
to reassign the user.
taskInstance.setActorId("newuser", true);
However finding the correct taskInstance is a issue that I am looking into at
the moment.
Sorry for the long winded explanation, but wanted to give you the full picture
of what I was talking about so you can decide how far you wanted to take it.
I need to do re-assignments as well because sometimes I will only have 1 actor
in a group.....:( Just found that out....
Hope this helps.
