Hi All,
When a class has one-to-many relation with 2 sibling classes, and has cascade set to all, the siblings are being persisted with the primary key of the parent class and not their own.

detailed explanation:
I have a class Owner which has onetomany relations with 2 sibling classes (CalendarEvent and PlannerEvent, which extend TimedEvent).
When I try and persist the Owner, it always fails at the second onetomany mapping because it is trying to insert the primary key of the table timedevent into the child foreign key.

All the Ids are being generated using
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
using the auto-increment feature of mysql.
If you look at the sql:
There are 2 inserts into the timedevent table one for the calendar event and one for the planner event.

But the inserts into the link tables are using timedevent primary key instead of the subclass primary key.

Any help is appreciated.

Thanks,

Your mapping is wrong. Re-read the relevant sections of the ref docs. The most likely source of the error is the inverse many-to-one mapping: see section 21.2 of the 3.1 ref docs. If you can't figure it out, post your mapping: if possible, convert it to .hbm.xml format first, as annotations are much harder to read at a glance.

Hi tenwit !

Thanks a lot for support !
