Possible bug with To Dependent PK
---------------------------------
Key: CAY-1507
URL: https://issues.apache.org/jira/browse/CAY-1507
Project: Cayenne
Issue Type: Bug
Components: Core Library
Affects Versions: 3.0.1
Environment: All
Reporter: Michael Gentry
Attachments: CayenneTestToDepPK.tar.gz
When using the To Dep PK setting, a commit, followed by an update, followed by
another commit is failing with an Optimistic Locking Exception as the PK for
the parent/master record is null in the snapshot and a null PK can't be
matched. Turning optimistic locking off makes the issue go away (but then you
lose another feature).
Will attach project illustrating bug. It should also be noted that when I put
together a scaled down example to illustrate the bug with just User and Avatar
classes, the problem did not appear. When I added the Role class it
re-appeared. Somehow it seems having the extra relationship on the
parent/master record (User) triggered the bug.
