Hi Chuck,
I want to create an Interface(virtual) Entity which can be any Entity when I set it to the virtual Entity.
i.e :
VEntity virtualEnt = VEntity.createInstance(ec);
virtualEnt = EOperson;
virtualEnt takes all description classe and pk of EOperson.
If virtualEnt = EOCompany an take all attribute of EOCompany.
Here is what I want to do.
