Hi Andrew, This exception means that Cayenne was unable to resolve some foreign key referred to Address.id because this primary key wasn't there at the referring entity commit time.
You could check if the Address entity commits ok. If it is then something wrong with the relationship setup. Though I'm not sure what that could be. Hope this helps.
