Hi Juergen, I suspect that you need to assign the key on the other side of your 1:1 relationship, too. Another thing you could try doing is using the To Dep PK checkbox in the DbEntity Relationship panel to see if Cayenne will auto-copy your meaningful PK for you.
http://cayenne.apache.org/doc/to-dep-pk-checkbox.html I'm not sure if the To Dep PK will work that way, but it is worth a try. If you assign all the keys, though, it should work.
