Hi,
When persisting an Entity which contains a collection I recently got the following Exception:
Code:
org.hibernate.HibernateException: Found two representations of same collection: khdb.entities.KladdenEntry.verkaeufe
at org.hibernate.engine.Collections.processReachableCollection(Collections.java:175)

at org.hibernate.transaction.JDBCTransaction.commit(JDBCTransaction.java:137)
at khdb.util.DTExecutor.startExecution(DTExecutor.java:31)
However the code in question looks like:
Code:
KladdenEntry e = new KladdenEntry();
e.verkaeufe = new ArrayList();
session.persist(e);
How can a duplicate representation of the collection exist if it's initialized to an empty ArrayList right after initialization.
Any idea why hibernate gets fed up? ;)
Thanks, Clemens
