Hi ,there i´m a new Hibernate user!
I have this error when i simulate a situation where i try to update an object Destino in PessoaDestinada on a second session.
Hibernate tries to find it on PessoaDestinada table.
There is another way to know if an object is still on database
not using locks nor update !?
Sorry by my english and thanks!
