Hello,

I have a great problem:

Master-detail-data is mapped as an idbag (lazy, with order-by-clause)

Reading a master with some detail elements is no problem.
Afterwards one detail element is modified,
and one new element is added AT POSITION 0 !! -> coll.add(0, newElem);

After saving (master) some of the detail elements are missing in the database.
Only two are left there, the new element and a some mix of the the others.

When adding at the end of the list everything is fine. -> coll.add(newElem);

Is this a hibernate bug ? What can I do ?
