--------------------------------

             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).
