[hibernate-issues] [Hibernate-JIRA] Created: (HHH-3590) Having @version in Parent causes wrong HQL update when updating subclass in Joined Subclass Inheritance Strategy.

Having @version in Parent causes wrong HQL update when updating subclass in Joined Subclass Inheritance Strategy. ----------------------------------------------------------------------------------------------------------------- Key: HHH-3590 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3590 Project: Hibernate Core Issue Type: Bug Components: query-hql Affects Versions: 3.3.1 Environment: Java 1.5 , Oracle 10g , Hibernate 3.3.1.GA Reporter: Rachit Priority: Blocker A very simple joined subclass strategy implemented. 2 classes: Employee(parent/superclass) and Person( child/subclass) Employee has @Version defined on column ROW_VERSION and Person extends Employee using Joined Inheritance Strategy. Person has PERSON_ID as PK and Employee has EMPLOYEE_ID as PK. I also have @PrimaryKeyJoinColumn(name = "PERSON_ID", referencedColumnName = "EMPLOYEE_ID") for obvious reason. Now if I update any attribute in Child class i.e Person.setVIPFlag("Y") , hibernate fires an update query on Parent entity with wrong column name in hql. In this case the query would be "update EMPLOYEE set ROW_VERSION=? where PERSON_ID=? and ROW_VERSION=?". This query fails as EMPLOYEE does not have PERSON_ID. The moment I remove @Version annotation from Parent(Employee) class, there is no update ( as expected ) and hence no error, but this is not an acceptable solution.
