One important design goal for z3c.form is not to be JS dependent. This is what
we developed z3c.formjs for.
Also, remember that a widget is something different in z3c.form. Taking the
E-mail widget example, we still only have a TextFieldWidget but might have a
specific EMailValidator registered for this widget.
From this point of view, I think it would be cool, if we could have a
ConfirmationWidget, which simply displays another widget twice. This
could then either be a PasswordWidget or TextFieldWidget. The cool part about
it is that the constructor of the confirmation widget could be smart to take
the passed in field into account.
So here is how I would like this to look:
widget = None # The widget that we want to display twice.
def FieldConfirmationWidget(field, request):
widget = FieldWidget(field, ConfirmationWidget(request))
widget.widget = zope.component.getMultiAdapter(
(field, request), IFieldWidget)
The challenge is to have unique names for the widget and its confirmation and
do all the updating correctly. You probably also need a custom validator that
first compares the two values to be equal and then forwards the validation.
I would love to see this widget in z3c.form. Of course, I am also still
waiting for the ObjectWidget. :-)
