[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-7046) Polymorphic query by natural ID broken

Polymorphic query by natural ID broken -------------------------------------- Key: HHH-7046 URL: https://hibernate.onjira.com/browse/HHH-7046 Project: Hibernate ORM Issue Type: Bug Affects Versions: 4.1.0 Environment: Hibernate 4.1.0 Reporter: Emanuel Kupcik I have a simple class hierarchy that is mapped as joined subclass class Principal { String uid; } class User extends Princpal { } class Group extends Princpal { } Till 4.0 it was possible to retrieve a user the natural ID using a criteria query for User.class and using uid as natural ID. In 4.1 this fails because Hibernate complains that column user_.uid doesn't exist. I can can still retrieve the user by using a criteria query for Principal.class. So this works Criteria loCriteria = loSession.createCriteria(Principal.class); loCriteria.add(Restrictions.naturalId().set("uid", aUID)); and this no longer works Criteria loCriteria = loSession.createCriteria(User.class); loCriteria.add(Restrictions.naturalId().set("uid", aUID)); Hibernate knows the correct name of the column from the mapping file but in the end it looks for it in the wrong table
