[hibernate-issues] [Hibernate-JIRA] Updated: (ANN-526) Type aproximation and unbound type limitation

Type aproximation and unbound type limitation --------------------------------------------- Key: ANN-526 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-526 Project: Hibernate Annotations Type: Bug

Versions: 3.2.1 Reporter: Sebastian Kirsch Assignee: Paolo "Nusco" Perrotta Priority: Minor Attachments: Hibernate ANN-526.zip, Hibernate-ANN-526_SecondCase.zip I get this "Property reference has an unbound type and no explictit target entity" exception and I think this is not exactly true. I'm not sure if this is a bug or a feature requests though. Have a look at the attached files and read on. I guess the model ist pretty easy to understand. The AbstractGeneric allows my to have concrete entities referring to specifc other subclasses - as seen in ConcreteOther and ConcreteSelf. The test case "workingClasses" shows us that Hibernate may work with this model - note that the class AbstractGeneric itslef was NOT added to the configuration. Now for the problem: The class OtherEntity is a completly different entity, but it refers to instances of AbstractGeneric - to any subclass of it actually, as AbstractGeneric is obviously abstract. If you run the test case "otherClass" the first part states that Hibernate doesn't know AbstractGeneric - which is fine, so I add that class to the configuration and try to build a session factory again. Now we receive the beforementioned exception. That's the situation. So is AbstractGeneric really an unbound type? I'd say it is not - T has an upper bound which should be good enough to work with - we know the table and the PK...
