Description

I ran into an issue with prefetching a belongs-to relationship whose target was the sub-entity of a vertical inheritance scenario. When disjointById is used, the select for the sub-entity looks for an ID of null instead of the actual ID assigned to the relationship.

For example, lets say I have a base entity Base, a vertically inherited sub-entity Impl, and a separate entity called Other.

If Other has a belongs-to relationship to Impl called Other.impl, attempting to use a disjointById prefetch on that relationship will always find no results.
