> *system9_.ORDER_BY*
> the errors are
> - SQL Error: 1791, SQLState: 42000
> - ORA-01791: not a SELECTed expression
> the generated SQL is wrong because it add system9_ and no need for it, it has already system3_
> there is a column in System bean called orderBy
> the hierarchy of beans like this (Service --> Module --> Component --> System)
> i attached the beans and mapping
> *NOTE: the hql works fine on Hibernate 3.4*
