Hi Anjo,
No, the primary keys are not class properties in either table. In other
words, they don't have the "diamond" checked in EOModeler which would
make them readily visible to the application.
This is the way it should be right? :-)
Thanks in advance,

Is your primary key a class property?
Cheers, Anjo
