Hi Paul,
Thanks for the clarification.
I overlooked "Account account = entityManager.find(Account.class, 215L); "
The above statement is supposed to return a proper entity object in return.
I would assume the original code in problem description should work fine.
I will try to run it against oracle XA driver and see if I can replicate the
problem.
Regards,
Ravi.
"unmanaged" means the Account object assigned to the ManyToOne field is
new and not yet persistent, removed, or detached.
