hi
in this part of code :
...
FleetUser fu = (FleetUser) QueryUtils.getNamedQuerySingleResult(em,
"FleetUser.findFleetUserForFleet.indexed", fleet);
em.remove(fu);
em.flush(); // HAVE TO FLUSH HERE
FleetUser newFu = new FleetUser(fleet, user);
fleet.setIsManaged(true);
em.persist(newFu);
...
...
If i remove the em.flush() call, when ending the transaction, an insert is done
before the delete and fails cause of an unique contraint on a FLEET_ID column
(to simulate one-to-many relation with association table).
Why is the delete delayed after the insert or not done at all ?
Christophe.
