----------------------------------
Summary: Vertical Inheritance: Updating one-to-many with inverse
nullifies other columns.
Key: CAY-2848
URL: https://issues.apache.org/jira/browse/CAY-2848
Project: Cayenne
Issue Type: Bug
Reporter: Jadon Hansell
Attachments: update-flattened-relationship-nullify-other-columns.patch
When there is a one-to-many relationship on the child DbEntity of a vertical
inheritance scenario, giving it an inverse fails when the relationship is
updated to anything non-null.
An update query is issued that contains the PK of the child row and the new ID
for the relationship, but sets every other column to null. I've included a
breaking test as a patch in 4.2-STABLE.
