Dear All,
I set the PersistenceOptions.CASCADE_POLICY_ON_CONTAINMENT, "FALSE",
because if I had a relation between 2 Objects (from diffrent resources)
and I delete relation, only the relation should be deleted not the
inheritance Object. Now, if I create a new Object and try to Persist it a
14372 [main] ERROR org.hibernate.event.def.AbstractFlushingEventListener
- Could not synchronize database state with session
org.hibernate.TransientObjectException: object references an unsaved
transient instance - save the transient instance before flushing: Lager
will appear.
The following Command works really fine but if i persist exception above
occur
Lager lager = ZlvpFactory.eINSTANCE.createLager();
lager.setName("Neues Lager");
Command cmd = null;
if (obj instanceof Jahr) {
cmd = AddCommand.create(service.getEditingDomain(), (Jahr)obj,
ZlvpPackage.Literals.JAHR__LAGER, lager);
}
if (cmd.canExecute()) {
service.getEditingDomain().getCommandStack().execute(cmd);
} else {
throw new ExecutionException("Fehler beim Anlegen des Lagers");
}
If I set PersistenceOptions.CASCADE_POLICY_ON_CONTAINMENT, "true" all
works fine but the inheritance Object will be deleted.

Hi Waldi,
FALSE is not a valid value for this option. But maybe you mean the SET_CASCADE_ALL_ON_CONTAINMENT option?
In this case I would set the PersistenceOptions.CASCADE_POLICY_ON_CONTAINMENT option to the following values:
REFRESH,PERSIST,MERGE
