[hibernate-issues] [Hibernate-JIRA] Commented: (EJB-240) attribute-override and embedded in orm.xml not working

[Thomas Risberg (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/EJB-240?page=comments#action_24854 ] 

Thomas Risberg commented on EJB-240:
------------------------------------

The attribute override is ignored so I get duplicate column name errors:

Exception in thread "main" javax.persistence.PersistenceException: org.hibernate.MappingException: Repeated column in mapping for entity: jpatest.Employee column: street (should be mapped with insert="false" update="false")
	at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:698)
	at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:121)
	at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:51)
	at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:33)


If I only have one embedded field then I don't get the duplicate error.  However, the override does not kick in - the default column names are used.

> Embedding an Address class twice and need to override the column names.  Using orm.xml and <embedded> plus <attribute-override> does not work while the same construct works using annotations.  The orm.xml works in the RI.
