Thanks Demian,
I was adding users but no groups. But I still have the problem with a group added.
Hibernate: select task0_.id as col_0_0_, deadline1_.id as col_1_0_, deadline1_.deadline_date as col_2_0_ from Task task0_, Deadline deadline1_ where (deadline1_.id in (select startdeadl2_.id from Deadline startdeadl2_ where task0_.id=startdeadl2_.Deadlines_StartDeadLine_Id) or deadline1_.id in (select enddeadlin3_.id from Deadline enddeadlin3_ where task0_.id=enddeadlin3_.Deadlines_EndDeadLine_Id)) and deadline1_.escalated=0 order by deadline1_.deadline_date
Hibernate: insert into OrganizationalEntity (DTYPE, id) values ('User', ?)
Hibernate: insert into OrganizationalEntity (DTYPE, id) values ('User', ?)
Hibernate: insert into OrganizationalEntity (DTYPE, id) values ('User', ?)
