Jadon Hansell created CAY-2855: ---------------------------------- Summary: Vertical Inheritance: Fix Disjoint By Id Prefetch On Sub-Entity Key: CAY-2855 URL: https://issues.apache.org/jira/browse/CAY-2855 Project: Cayenne Issue Type: Bug Affects Versions: 4.2 Reporter: Jadon Hansell Attachments: disjoint-by-id-issue.patch
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. -- This message was sent by Atlassian Jira (v8.20.10#820010)
