Try something like:
# You need the form instantiated only once and return the same
# instance as the one passed to "validate"
form = widgets.TableForm(
fields = [
# stick your validators in the form's fields
widgets.TextField("number", validator=validators.Int(),
label=...),
]
def newForm(self):
return dict(form=form)
# Branch to "newForm" if validation fails so the form is redisplayed
with
# previous input and errors
@error_handler(newForm)
# validate input using the form's schema
@validate(form=form)
def processForm(self, number):
# number is a int if execution reaches this point
....
