Emmanuel Bernard resolved ANN-437:
----------------------------------
Resolution: Rejected
> @IndexColumn does not work with discriminator-inheritance on the target entity of the list
> ------------------------------------------------------------------------------------------
>
> Key: ANN-437
> URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-437
> Project: Hibernate Annotations
> Type: Bug
> Versions: 3.2.0.cr1
> Reporter: ron piterman
>
>
> When using inheritance on the target entity of a List, @IndexColumn annotation does not work. Hibernate does not populate the index column value on the target entites. As a result, the sort_order column is null.
> (In the code example below a generator for the @ID is missing.)
> @Entity
> public class PropertyOwner {
> @Id
> private Long id;
> @OneToMany(mappedBy="owner",cascade=CascadeType.ALL)
> @IndexColumn(name="sort_order")
> private List<AbstractProperty> properties;
> ...
> }
>
> @Entity
> @DiscriminatorColumn(name="property_type",discriminatorType=DiscriminatorType.STRING)
> public abstract class AbstractProperty {
> @Id
> private Long id;
> @ManyToOne
> private PropertyOwner owner;
> }
> @Entity
> @DiscriminatorValue("integer")
> public class IntegerProperty extends AbstractProperty {
>
> int integerValue;
> ...
> }
> @Entity
> @DiscriminatorValue("string")
> public class StringProperty extends AbstractProperty {
>
> String stringValue;
> ...
> }
