You do not have cascade delete set in hibernate do you? I don’t think LC DS would delete items if you are just removing an item from a collection or set an association to null. In general, just calling “deleteItem” on the child should remove it from the parent’s child property automatically.
If you are not running on the latest hotfix it might be worth trying that as there have been a few bugs fixed in that version. I’ll send you a copy off list.

All works correctly, but when I try to delete one of the child objects (either by parent.childs.removeItemAt() or directly through dsChild.deleteItem()), my parent object just disappears - it is deleted as well. I can fix this by making the relationship one-directional (then it works), but I think there has to be some setting either in LCDS or in Hibernate to prevent this. Thanks in advance for some advice Zdenek M
