I have 2 teams of users - team A and team B.
I want to stop members of team A assigning to members of team B and vice versa and force them to use the existing workflow transitions to move issues between teams.
I've tried programmatically setting the jira.permission.assignable.group property but it seems to have no effect.
Ideally the assign user list would only contain their own team's co-workers, this would encourage them to looks for a workflow option.
