Working with forms in CAPI

Hello,

I have a form in the spirit of an address-book contact sheet which has been defined with define-interface.  On the other side I have a Contact object, and I would like to assign this object to the form in order to populate the different user interface elements.

I have tried different options but none of which gave me satisfaction.
I would like to know how seasoned CAPI users implement encapsulation with regards to CAPI interfaces.


Thanks!

Best Regards,
Camille
