Catalina Wei commented on OPENJPA-961:
--------------------------------------

Support for elment collection within embeddable is checked in under r759330.
Examples:
    
    select e from EntityA_Embed_Coll_Embed a , in (a.embed.embeds) e

where EntityA_Embed_Coll_Embed contains an embeddable object "embed" and that embeddable object contains an element collection.

> 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);
