Just a little modification from Peter's code
Instead of defining an object attribute in the Variable and Expression, leave
it blank so 4D will generate a dynamic variable for it. In the object method,
you just need to execute the following when the On Data Change occurs.
Case of
: (FORM Event=On Data Change)
Form.en_edit.contact:=Self->
End case
HTH,

Another possibility - I have not tested it, so I am not 100% sure it would
work - would be not to assign Form property to object, and rather leave
the expression empty. Then you would have Self-> and could get pointer to
object with OBJECT Get pointer (object named;) call.
However, you would have to bind the object to the form property yourself,
with code like
case of
:((form event=on load) | (form event=on outside call))
Self->:=Form.en_edit.contact
:(form event=on data change)
Form.en_edit.contact:=Self->
end case
