[news.eclipse.rt.eclipselink] Re: Problem with Foreign Composite Key sha

[james.sutherland@xxxxxxxxxx (James )]

This should work, you can make half the foreign key read-only.  If you 
remove the insertable/updateable=false, or move the false to be the second 
JoinColumn does it work? (you may need to add an @Column with 
insertable/updateable=false for the @Id owner).

If it does, then please log a bug for this.

Another workaround would be to add another basic variable for the other 
foreign key, or use a DescriptorCustomizer to fix the OneToOneMapping's 
foreign key fields.
