##############################################

I tried to make the example as short as possible in order to reproduce my problem. Basically I got a Calculation object which contains a AmountSchedule and a Schedule objects ; AmountSchedule is a subclass of Schedule.

When trying to insert a calculation object, Hibernate try to persist both a AmountSchedule and a Schedule objects ; unfortunately for an unknow reason (at least for me), it seems that the same native id is generated (4 in the traces) for the two objects.

Maybe I'm not using the good id generator, maybe my mapping is wrong but as a new user to Hibernate I can figure out what it may come from.

PS : The classes and hbm files are all generated with hyperxajb2 version 0.2

Any help is welcome. For more precison don't hesitate to ask :)

usally this means that the object was already previously loaded into your session, and you are trying to use a detached object with same ID in your session.
