Guys,

I've been reading the Hibernate reference documentation and I'm having some questions on the following,



The call to update makes a detached object persistent again, you could say it binds it to a new unit of work, so any modifications you made to it while detached can be saved to the database. This includes any modifications
(additions/deletions) you made to a collection of that entity object.

When they call update, they are already in a Hibernate session (the session2 object), then how they say that it is in detached state? Please clarify me...

Thanks in advance!
