The translator records it with `registerSelectionAlias`, and `getFullyQualifiedExpression` ignores that map. The lookup returns null, or an entity property of the same name. Expose the selection alias on this context. Do not change predicate property resolution. Please order by a `sqlProjection` alias and assert the projected expression is used. -- This is an automated message from the Apache Git Service.
