Hello!
I'm running on envers 1.2.1 and Hibernate 3.3.2.
My inheritance strategy is SINGLE_TABLE (discrim).
I have two problems, when running polymorphic queries against the auditreader:
1. query for parentTypes does not instantiate childtypes
I get wrong types instantiated in the result.
The testcase "\src\test\java\org\hibernate\envers\test\integration\inheritance\single\ChildAuditing.java"
passes, but when I change the two sides of the equals method in testPolymorphicQuery()'s second assert the testcase fails, because
the expected result is a ChildEntity, but in the result we get an instance of ParentEntity.
your assert (passes)
assert getAuditReader().createQuery().forEntitiesAtRevision(ParentEntity.class, 1).getSingleResult().equals(childVer1);
my assert (fails)
assert (childVer1).equals(getAuditReader().createQuery().forEntitiesAtRevision(ParentEntity.class, 1).getSingleResult());
2. problems with abstract entities
Similar to the defect with private constructors (http://opensource.atlassian.com/projects/hibernate/browse/HHH-3736) the queries for abstract entities fail with NullPointerException.
Probably both problems should be fixed in the method EntityInstantiator.createInstanceFromVersionsEntity.
