You can try something like:
if form.vars.field1 == None:
form.custom.widget.field1.append(OPTION(form.vars.field2, _value=
new_value_id))
Note, that will simply append the new option to the list of options. If you
need it to be inserted at a particular location in the list, the code will
get a little more complicated.
