--------------------------------
Summary: Various Update Issues With Vertical Inheritance
Key: CAY-2282
URL: https://issues.apache.org/jira/browse/CAY-2282
Project: Cayenne
Issue Type: Bug
Components: Core Library
Affects Versions: 4.0.M5
Reporter: Matt Watson
Attachments: breaking_test.patch
The two tests in the attached "breaking-test" patch show the two scenarios that
are broken.
1) {{testUpdateTwoObjectsWithMultipleAttributeAndMultipleRelationship}} :
breaks because of the relationship change. Without changing relationship the
update actually works fine. But with the relationship change its going through
{{DataDomainIndirectDiffBuilder.arcDeleted}} and
{{DataDomainIndirectDiffBuilder.arcCreated}} thus creating flattened Insert and
Delete statements instead of an UPDATE statement.
2) {{testUpdateWithOptimisticLocks}} : breaks because the vertically inherited
ObjEntity has an attribute using Optimistic Lock for a field that is actually
on the parent DbEntitity, and the Update query that is built is incorrectly
referencing the column on the wrong table for the {{qualifierExpression}}.
I actually already have a fix ready for this 2nd issue, but want to get both of
these issues fixed in this ticket, so anyone helping on this issue please focus
on fixing the first test.
