Support projection of element collection from a JPQL query
----------------------------------------------------------

                 Key: OPENJPA-961
                 URL: https://issues.apache.org/jira/browse/OPENJPA-961
             Project: OpenJPA
          Issue Type: Sub-task
          Components: jpa
    Affects Versions: 2.0.0
            Reporter: Jeremy Bauer
            Assignee: Catalina Wei


This task is to support projection of element collection elements within a JPQL query.  Ex.
 (SELECT b FROM ColEnt a JOIN a.coll b)  where coll is an element collection within entity
A.  There are some assertions commented out in TestOrderColumn.java that use JPQL for validation.
 They can be used to help test this task.

// This validator is disabled until INDEX projection supports element 
// collections
//        validateIndexAndValues(em, "BaseTestEntity", "collelems", 10, 
//                new Object[] { elems[0], elems[1], elems[2]} "id",
//                bte.getId());

and 

//      This validator is disabled until INDEX projection supports element 
//      collections
//        validateIndexAndValues(em, "Owner", "bikeColl", 0, 
//                bikeArr, "id", 
//                oid);
