Naturally I read the document but I can say that it is not behaving like it is there described, at least not with jbpm console
For ex...
'11.7. Swimlane in start task
A swimlane can be associated with the start task to capture the process initiator.
A task can be specified in a start-state. That task be associated with a swimlane. When a new task instance is created for such a task, the current authenticated actor will be captured with Authentication.getAuthenticatedActorId() and that actor will be stored in the swimlane of the start task.'
That is definitely not happening, the group that I defined for the swimming lane is assigned to the task as ActorPool but Task is not assigned to the actually authenticated user, I have to do that manually....
To make the thing worse, I can assign an actor that is not belonging to the group defined in the swimlane and jbpm doesn't complain about that also....
