[hibernate-issues] [Hibernate-JIRA] Moved: (ANN-708) id class columns not honored when using orm.xml

id class columns not honored when using orm.xml ----------------------------------------------- Key: ANN-708 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-708 Project: Hibernate Annotations Issue Type: Bug Components: binder Reporter: Adam Hardy Attachments: jpabug.zip Hibernate EntityManager won't map an id-class for an entity. I have ust one entity with an inner class as the idClass. Hibernate refuses to load the entity, throwing the following exception (see further down). I am using hibernate-annotations-3.3.0ga and hibernate-entitymanager-3.3.1ga.
