Nested embeddable with a relationship to an Entity with a generated id doesn't persist the
relationship
-------------------------------------------------------------------------------------------------------

                 Key: OPENJPA-1072
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1072
             Project: OpenJPA
          Issue Type: Bug
          Components: jpa
    Affects Versions: 2.0.0
            Reporter: Rick Curtis
         Attachments: jpa.embeddables.zip

When working with embeddables I found that if I define a unidirectional @ManyToOne relationship
from an embeddable to an Entity which has a generated id, the relationship in the join table
doesn't get persisted. I'll attach a zip with my code, but I'll also try to describe the scenario
here.

Entities: 
Seller - Has an auto generated ID and a name
Book - Has an id(isbn) and an ElementCollection of Listings
Listing - An embeddable that has a ManyToOne relationship to Seller, a price and comments.

The scenario is as follows:
* Create all the sellers.
* Create a book.
* Add a listing to each book. Each listing takes a Seller Entity and a price.
* When I commit the book, the seller_id column in my Listing join table is always zero.
