Catalina Wei resolved OPENJPA-961.
----------------------------------
Resolution: Fixed
Fix Version/s: 2.0.0
work remains to complete full support of element collection in query;
when an identification variable is defined over an element collection, this
identifier can appear as an argument of INDEX or TYPE functions, or could be
referenced is where clause or further navigated down the path.
These will be address in sub-task of iteration 6.

>
> 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);
