I have read the doc and the forum and am looking for a little help. I have three classes BookshelfItem, MemeberProfile, and BookDetail. On all three I want to specify a key for the id within the program. I have specified the relationship as <many-to-one> and cascade='all' for both child classes.

BookshelfItem --n-----1-->MemberProfile
BookshelfItem --n-----1-->BookDetail

Out of the gate when I called session.save(BookshelfItem) the only thing saved was the BookshelfItem, the MemberProfile and BookDetail objects were not saved. I turned on debugging and what is see is that an insert is called on BookshelfItem and update is called on the two child objects. I did not expect this since I called session.save(...) instead of session.saveOrUpdate(...). I saw where I can set the unsaved-value on the child classes but this forces me to hadle either the save() or update() case manually on the child objects - which I would rather not do. Is this the expected behavior - should not the save() operation be cascaded to the child objects as save() instead of saveOrUpdate()?

Thanks
