--------------------------------------
This also affected {{EJBQL}} queries, added test case per
https://github.com/apache/cayenne/commit/4a6241641f66a55b83f65e2b4c124e0f74d95121
> ColumnSelect: unable to use from nested context
> -----------------------------------------------

> Key: CAY-2363
> URL: https://issues.apache.org/jira/browse/CAY-2363
> Project: Cayenne
> Issue Type: Bug
> Components: Core Library
> Affects Versions: 4.0.B1, 4.1.M1
> Reporter: Nikita Timofeev
> Assignee: Nikita Timofeev
> Fix For: 4.0.B2, 4.1.M1

>
> 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.
