JPQL extension: aggregates in ORDER BY
--------------------------------------

                 Key: OPENJPA-490
                 URL: https://issues.apache.org/jira/browse/OPENJPA-490
             Project: OpenJPA
          Issue Type: New Feature
    Affects Versions: 1.0.1, 1.0.0, 0.9.7, 0.9.6, 0.9.0
            Reporter: Patrick Linskey
             Fix For: 1.1.0


JPQL only allows state fields in ORDER BY clauses. It is useful to order by 
aggregates when doing a GROUP BY as well. Example:

select sum(o.shortField) from AllFieldTypes o
    group by o.intField 
    order by sum(o.shortField) asc
