[hibernate-issues] [Hibernate-JIRA] Updated: (METAGEN-77) Inheritance of metamodel classes

Inheritance of metamodel classes --------------------------------- Key: METAGEN-77 URL: http://opensource.atlassian.com/projects/hibernate/browse/METAGEN-77 Project: Hibernate Metamodel Generator Issue Type: Bug Components: processor Affects Versions: 1.1.1.Final Environment: hibernate 3.6.7, oracle 11g Reporter: Peter Dragula Assignee: Hardy Ferentschik Priority: Minor Labels: jpa2, metamodel Fix For: 1.2.next If there is Inheritance structure like: @Entity (No entity annotation) @Entity public class Party extends public abstract Timelimited extends public abstract Versioned String name Long timelimitedId Long versionedId Date date Long partyId the model generator generates Party_ with only name date and partyid (no extends ) then it generates Timelimited_ with timelimitedId , but also without any parents (no extends) and lastly a Versioned_ is generated with versionedId Now I would like to say Party_.versionedId , but i cant A workaround is to annotate the Timelimited class (which is in the middle of the hierarchy) with a @Entity then the Party_ extends Timelimited which extends Versioned and everything works as desired but JPA allows to have non entity classes in the middle of a hierarchy : Both abstract and concrete classes can be entities. Both abstract and concrete classes can be annotated with the Entity annotation, mapped as entities, and queried for as entities. Entities can extend non-entity classes and non-entity classes can extend entity classes:
