[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-5183?page=c... ] Emmanuel Bernard updated HHH-5183: ---------------------------------- Description: When @SecondaryTable is declared (with the same secondary table name) in 2 distinct entities that belong to the same hierarchy (single table inheritance), hibernate considers that the secondary tables are different! Indeed, when persisting the entity, if the properties (using the secondary table) are set in the entity itself and its parent, hibernate does 2 inserts on the secondary table instead of one (one for the 'secondary' property of the parent, and one for the 'secondary' property of the current entity) This triggers a pk violation exception as the same PK is used twice on the secondary table. was: When @SecondaryTable is declared (with the same secondary table name) in 2 distinct entities that belong to the same hierarchy (single table inheritance), hibernate considers that the secondary tables are different!

Affects Version/s: (was: 3.3.2) 3.5.1 Component/s: core Issue Type: New Feature (was: Bug) Summary: Use the same @SecondaryTable on a class and its subclass (was: Inheritance (single table) and @SecondaryTable ) Actually this is something we explicitly do not support today. It looks super wrong if you ask me (either your db schema or your inheritance approach). I am not sure how easy core can cope with de-duplicating the tables and jungle between the entity and its subclasses. But that may be possible.
