From what I understand, it might be a good idea to define a method to
retrieve the PK in the lower level generated class (which is normally
empty).
It's explained on the
http://www.objectstyle.org/cayenne/userguide/dataobjects/unmapped-keys.html
page.
When you have access to your PK, you can use it in expressions like any
other attribute.
I'm curious, though: why in the world would you need to include two
criteria, when one of them uniquely identifies a record?
