Subject Re: EJBQL client-side challenge
Date Tue, 26 Jan 2010 13:52:07 GMT
Does the scenario at
org.apache.cayenne.CayenneContextEJBQLTest.testEJBQLSelect() satisfy to the
conditions you are talking about?
Because in such a case we have the DbEntity with name "MT_TABLE1" and the
ObjEntity with name "MtTable1" - they are different, aren't they? This test
successfully passes with query "SELECT a FROM MtTable1 a", and fails on
query "SELECT COUNT(a) FROM MtTable1 a" but not for the reason that you
have, but because there is a problem with the processing scalar results.
 Could you give a more concrete example if I misunderstood the problem?
