[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2764) EntityType.deepCopy needs to copy for EntityType.DOM4J

EntityType.deepCopy needs to copy for EntityType.DOM4J ------------------------------------------------------ Key: HHH-2764 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2764 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.2.2 Environment: Hibernate 3.2.2 Reporter: Alan Krueger Using DOM4J with a set of composite-elements that contains a many-to-one. When loading this from the database, the many-to-one piece of the composite-element is disappearing from the XML. I can see the collection being built and the properties on the elements of the collection being set, but the many-to-one property disappears after that. Investigating this, it looks like when PersistentElementHolder.getSnapshot is called and a deepCopy is performed, the EntityType.deepCopy method returns the value to be copied rather than copying it. This interacts poorly with the DOM4J tree, since each Element can only have a single Element parent. When the properties are set on this, a detach is performed that yanks the original element out of its parent.
