simple session.lock question

What happens if you use session.lock() on a detached object that has been modified?

That depends on the lockmode that you specify.

I've already read that. The docs say you should only use session.lock() if you're sure that the object hasn't been modified. So what happens if you reconnect an object that was modified? An error? Overall weird behavior?

Well, lets say you use session.lock(myObject, LockMode.NONE)

This will reassociate your detached object with the session.

Did you read the following:
http://www.hibernate.org/hib_docs/v3/re ... ns-locking

I realize it can be a bit confusing but I think this page answers your question.

If not, try asking it another way or giving a usage example and I'll try to help.

Hi Kds, did you ever find an answer for your question (what are the consequences of reassociating a modified object with LockMode=NONE) ?
