[hibernate-issues] [Hibernate-JIRA] Resolved: (ANN-569) Map the same class twice in orm.xml

From what I understand, Gavin wanted to push it and the initial API proposal had it. Then the feature was removed (but the - empty - notion remained)

Map the same class twice in orm.xml ----------------------------------- Key: ANN-569 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-569 Project: Hibernate Annotations Type: New Feature

Components: binder Reporter: Christian Bauer Priority: Minor

Regular annotated class, I'd like to map it again in orm.xml with a different set of persistent attributes (they are annotated transient in the regular class): <!-- If I don't have the regular class mapped here, I get only a NODE_HISTORY table. I want two tables. --> <entity class="Node" name="RegularNode" access="FIELD"> <table name="NODE"/> </entity> <entity class="Node" name="HistoricalNode" access="FIELD"> <table name="NODE_HISTORY"/> <attributes> <id name="historicalNodeId"> <column name="NODE_HISTORY_ID"/> <generated-value/> </id> <basic name="revision" optional="false"> <column name="NODE_REVISION"/> </basic> <basic name="id" optional="false"> <column name="NODE_ID"/> </basic> </attributes> </entity> I currently only have 3.2.0 CR1 (Seam...) here: [hibernatetool] javax.persistence.PersistenceException: java.lang.IllegalStateException: Duplicate XML entry for org.jboss.seam.wiki.core.node.Node [hibernatetool] java.lang.IllegalStateException: Duplicate XML entry for org.jboss.seam.wiki.core.node.Node If the spec forbids duplicate class names in orm.xml (does it?) - how can I override mappings under a different entity alias?
