Hi,

So the problem is that reverse engineering of relationships doesn't  
work, right? If that's the case, could you doublecheck that you have  
foreign key constraints defined properly in the database. Otherwise  
Cayenne won't be able to guess the relationships correctly.

Also there may be a problem with MySQL - Cayenne prior to 3.0 assumed  
that MySQL does not support FK constraints and simply ignored their  
existence. So if you are indeed on MySQL you may try using Cayenne  
3.0 M1.
