thomas menzel commented on HHH-4329:
------------------------------------
any inclination to work on this issue or provide a decent workaround?
> @ForeignKey override of @MappedSuperclass
> -----------------------------------------
>
> Key: HHH-4329
> URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4329
> Project: Hibernate Core
> Issue Type: New Feature
> Components: annotations
> Reporter: Christian Bauer
>
> Put this @ManyToOne in a @MappedSuperclass:
> @ManyToOne(fetch = FetchType.LAZY)
> @JoinColumn(name = "CREATED_BY_USER_ID", nullable = false)
> // Ideally this foreign key should be ON DELETE SET NULL, however...
> // Hibernate can't rename these so subclasses would get the same FK constraint name. This doesn't
> // work, so we need to let Hibernate create a random identifier for these. We could fix this in the
> // DatabaseObjects.hbm.xml file but we can't even address it because the name is random. This sucks.
> // So we do a manual SET NULL|DEFAULT when userHome.remove() is called.
> // @org.hibernate.annotations.ForeignKey(name = "FK_WIKI_NODE_CREATED_BY_USER_ID")
> protected User createdBy;
> Now all subclasses get that foreign key constraint name in the database catalog, which isn't possible - constraint names have to be unique.
