Hi Ramiro,
By default, Cayenne does not map PKs into Java objects because they
are considered database artifacts.
What is the source of your idUser values (the 2,5)? If external to
your application, you can always manually add idUser back into your
ObjEntity in Cayenne Modeler.
If the source is really internal, you might want to consider matching
against user names or objects or other attributes.
