EM Incorrectly throws EntityExistsException wrapping ConstraintViolationException on constraint violation during delete ----------------------------------------------------------------------------------------------------------------------- Key: EJB-349 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-349 Project: Hibernate Entity Manager Issue Type: Bug Components: EntityManager Affects Versions: 3.3.1.GA Environment: Postgresql 8.2.7, Hibernate 3.2.4.GA, Hibernate EM 3.3.1.GA Reporter: Derek Chen-Becker When I attempt to delete an entity via a named query, and the entity has a foreign key constraint, the EM throws an EntityExistsException that wraps the real org.hibernate.exception.ConstraintViolationException: INFO - Service request (GET) /org/removeEmail.html took 89 Milliseconds WARN - SQL Error: 0, SQLState: 23503 ERROR - ERROR: update or delete on table "organization_email" violates foreign key constraint "fk_org_email" on table "organizations" Detail: Key (id)=(1) is still referenced from table "organizations". ERROR - EM Error javax.persistence.EntityExistsException: org.hibernate.exception.ConstraintViolationException: could not execute update query at org.hibernate.ejb.AbstractEntityManagerImpl.throwPersistenceException(AbstractEntityManagerImpl.java:605) at org.hibernate.ejb.QueryImpl.executeUpdate(QueryImpl.java:59) I checked the source code for 3.3.1 and revision 14382 of org.hibernate.ejb.AbstractEntityManagerImpl.java has a "FIXME" message on line 612 that basically indicates that this is a known issue. I couldn't find an existing bug on it in JIRA, so I apologize if this is a dup. In any case, is there any way for the EM to determine that the attempted statement was a delete and not an insert/update? -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
