Hello all,

            I'm wondering if OpenJPA supports the creation of a compound
primary key formed by a basic field, and a collection. I have tried
using an "Id class", and using "unique-constraint", but without any
results.

            I think this is a very basic feature (A foreign key is part
of the primary key) used frequently in any relational data model.=20

            Can anyone confirm this feature support?. Any simple example
would be very appreciated.

            Thanks in advance, regards.
