[Peter Dragula (JIRA)]

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


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:
