Nikita Timofeev commented on CAY-2363:
--------------------------------------

This also affected {{EJBQL}} queries, added test case per https://github.com/apache/cayenne/commit/4a6241641f66a55b83f65e2b4c124e0f74d95121

> Queries like this always failing:
> {code}
> ObjectContext nested = runtime.newContext(parentContext);
> ObjectSelect.columnQuery(Artist.class, Artist.ARTIST_NAME).select(nested);
> {code}
> {{ObjectContextQueryAction}} tries to cast result to {{Persistent}} and that is obviously
invalid in this case.
