> 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.
