[Twisted-Python] nuvow webform example?

I have another question about the docs in nuvow webform. I'm following
the tutorial for nevow and I want to create a dynamic form with model.


I see an example of the webform, but it doesn't quite work:

class WebForm(rend.Page):
#   document = rend.stan(  # this should be changed to:
    docFactory = loaders.stan(
        h1["Here is the form:"],
resource = WebForm(Implementation())

I'm not sure I quite understand why 'original' goes there, but in any
case, I don't get any output from this. Is there something else that
needs to be fixed with this example?
