Description James Sutherland CLA 2010-06-02 10:34:08 EDT 
If you mark a subclass mapping to use IN batch fetching, but none of the superclass mappings, nor the query, then the query will not know of the IN batch fetch and will not have stored the rows to provide the IN collection of ids.

Comment 2 James Sutherland CLA 2010-06-02 13:48:15 EDT 
Fixes issue.

In any subclass uses batch IN, parent is marked as using batch IN.

Also allow hints for subclass relationships, and aggregates
And throw better error when batch IN is missing.
