Hi,
Thanks for submitting this clue.
However, in my case it doesn't help since:
1) I need to have the ID of C entity inherited from the parent when saving a new parent entity (the id is created using Oracle sequence)
1a) For what I have found, this is ONLY possible in bidirectional 1:1
Setting this (1:1) relation as many-one on A and one-many on C results in a NullPointerException when processing Element Annotations..
(I suppose that might be because I still have):
| public EntityC getEntityC() {
| return entityC;
| }
and not
| public Set<EntityC> getEntityC() {
| return entityC;
| }
|
in my parent A entity...
On the other hand, making a bidirectional Set of real 1:1 relation doesn't make much sense to me :(
BR,
hoomey
