AndroMDA/JIRA Commented: (HIB-165) 'patch' for multiple unique keys

>
> I've added a 'patch' how to teach Hibernate multipele unique keys. Maybe you would like to integrate it into your cvs? It is based on 3.1 final.
> I've added a new tag called @andromda.persistence.column.uniqueGroup. This one will be mapped directly to hibernate's unique-key property. Attached you find the version for hibernate3, hib2 should be exactly the same.
