course groups: register users not possible
Using course groups:
users cannot be registered, cannot register themselves.
it seems that also the old selection system is used.
Alert: course group has not been updated. UserX maximum number of group subscriptions is reached.
However: number of subscriptions is high enough. (so the 'maximum number' reason does not apply.)
However: also with newly created groups the problem occurs (so the 'group not updated' reason does not apply.)
occurs in Desiderius 4.0
