Hi Carl,

Yes, until 3.0 the logic in Cayenne worked like this:
1. if you don't map PK as an object property, Cayenne will generate

2. if you do map it, you must provide it yourself.

Could you doublecheck the model making sure the 'toDepartmentPrefix'
relationship is still mapped?
I often get similar errors when I forget to refresh the source tree

Just to clarify, CAY-732 is a real bug, but it is not a bug with

The underlying cause is still the inability to build correct joins

I suspect this line copes ObjectId from another object, so Cayenne is
