[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-1152) Value object(<component>) inheritance mapping

[Jonni Gani (JIRA)]

Jonni Gani commented on HHH-1152:
---------------------------------

Just to echo Vjeran, component inheritance similar to entity inheritance would be good, though the one I'm particularly interested in is 'Table per class hierarchy' with a discriminator column. This issue should get a higher priority as it's essential for good model design with proper distinction between Entity and Value Object.

> Though fine-grained object mapping is one of Hibernate's main objectives, it still doesn't support *value object* (<component>) inheritance mapping, only entity inheritance mapping.
> It would be best if <component> tag could also contain similar tags for inheritance as entity does.
