Fix Version/s: (was: 4.x)
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.
