I ran into a similar problem a few days ago. I made the mistake to use entity inheritance + eager fetching on a list. It seems that this is not accurate. Because the @ColumnIndex approach did not work for me, I switched back to lazy fetching. In my app, this is not critical. If you want to know more, google for "multiple/simultaneous fetch". I'm not quite sure, but the Hibernate book calls the problem the "Cartesian product problem".
