nonuniqueexception when loading the same object multiple times
--------------------------------------------------------------

                 Key: HHH-2886
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2886
             Project: Hibernate3
          Issue Type: Bug
    Affects Versions: 3.2.5
         Environment: PostgreSQL 8.2
EHCache 1.2.4
            Reporter: Andreas Pakulat
            Priority: Critical


When using HQL or Criteria queries to find a specific object in the database it seems that Hibernate completely bypasses its Session Cache and thus creates new persistent objects each time the query is run. If the query however finds the same object multiple times this results in non-unique-exceptions as soon as one of the objects is updated.

Hibernate should check its session cache when loading objects from the database and use those already associated objects instead of creating new ones.
