[jboss-user] swimlanes and group assignment

hello, i'm hoping someone could clarify swimlanes for me. namely, if i have a swimlane that is assigned to a group, shouldn't tasks started by one user in the group continue to be visible to the group? if that's not default behaviour, is it possible to make it work like that (preferably without hacking the jbpm code). in other words, given swimlane a assigned to group x that includes bob and alice, when task is deployed, it is visible to both bob and alice. however, if bob starts an instance, it is no longer visible to alice, only bob. i want alice to be able to take over the task at any point, and vice versa. any help would be greatly appreciated. ~ea
