[twill] forms

[Norman Khine]

hello,
is there a direct way to check how many forms the page returned has?
from the docs:
showforms -- show all of the forms on the current page. When called
from Python, this function returns a list of the forms.

but if i do
b = twill.get_browser()
forms = b.showforms()
print len(forms)

i get
TypeError: object of type 'NoneType' has no len()

thanks
