[rules-users] Flow, Human Task, Group Assignment

Hi, I've got a question concerning drools flow, human tasks and group assignments. I assigned a human task to a group (via the groupId parameter) and can successfully retrieve it using the TaskServiceSession function: getTasksAssignedAsPotentialOwner(userId, groupIds, language) This function implies in my understanding that the knowledge about group membership is not (yet?) managed within the human task management component, otherwise there would be no need to pass the groupIds to it. If a user tries to claim the task now, a PermissionDeniedException is thown because drools currently has no information about his group membership. see TaskServiceSession, line 602: isAllowed(final User user, final List<OrganizationalEntity> entities) There is even a comment in there... "for now just do a contains, I'll figure out group membership later." Is there a way to work around this issue? I'd like to avoid implementing my own TaskServiceSession because of the lack of an interface and a dependency to SubTasksStrategies. Thanks in advance, Chris
