>We always had some mapping because of the DB vs. API object definition discrepancies. But bug 25260 revamps the reserves table, and it is a perfect match. It highlights this edge case: if no mapping defined, then and undef from_api_mapping is generated (as opposed to an empty hashref) and this leads to errors in the query translation from the API.
