Christian Bauer resolved HB-123:
--------------------------------

    Resolution: Won't Fix

This is all done in Hibernate 3.2. You can use a DISTINCT keyword or a ResultTransformer to hide the duplicates, if you want to. The new DISTINCT keyword filters the duplicate root entities in memory. Of course there is no way to "hide" them at the SQL row level, and that is also why thy are exposed by default.

> HQL fetch of an associated collection should return distinct entities.
> For example, the following HQL:
> "FROM Department dept LEFT JOIN FETCH dept.personnel"
> should return each department(with its associated collection) only once.
