Hello,

I have modelled a parent-child relationship. All is done according to the document that describes the parent chid relationship.

I have one parent and one child object which are connected to each other.

Everything works just fine, when I save the parent object with session.save(parent) the parent and child are inserted into the database. I was wondering how Hibernate reacts when I save the child object instead of the parent object. So I replaced the session.save(parent) by session.save(child) and ran my app again. I thought Hibernate knows how to handle this case, but I received the following exception

I just wonder why can't Hibernate handle this save order?

dee3lmo!

SORRY THE TITLE MUST BE 'I was wonder why Hibernate CAN'T handle this...'

because you didn't enable cascade save on the many-to-one association

Thanks gavin now it works!
I really appreciate that the Hibernate team reponse so quickly on issues of beginners!!!

next time you'd better write
'I was wonder why i CAN'T handle this knowing hibernate can do a lot of things...' ;))
