John Larson created CAY-2693:
--------------------------------
Summary: Abstract subentities do not have rows materialized
correctly
Key: CAY-2693
URL: https://issues.apache.org/jira/browse/CAY-2693
Project: Cayenne
Issue Type: Bug
Components: Database integration
Affects Versions: 4.1
Reporter: John Larson
Attachments: EntityInheritanceTree.java
Given an inheritance tree such as (qualifiers are in parentheses):
abstract class A
concrete class B extends A (type = 0)
abstract class C extends A
concrete class D extends C (type = 1)
concrete class E extends C (type=2)
and single-table inheritance.
When querying on class A and results include a row of type D,
EntityInheritanceTree will return C as the matching entity. In fact, even if
the results include a row of type B, if entityMatchingRow will return C if it
is checked before entity B.
Also, qualifierForEntityAndSubclasses will return a null qualifier for type C
when it should really return (type =1) or (type = 2).
