[hibernate] How do you create a Distinct query in HQL

I had some problems with result transformers combined with HQL queries. When I tried

final ResultTransformer trans = new DistinctRootEntityResultTransformer();
qry.setResultTransformer(trans);

it didn't work. I had to transform manually like this:

final List found = trans.transformList(qry.list());

With Criteria API transformers worked just fine.
