[Zope3-Users] nextURL not working as expected

I am using nextURL() in a similar fashion (only using create(),
no add part) and it works fine for me, i. e. I am redirected as
expected, see the code snippet below.

I guess with the line

    self.context[data["title"]] = self.link

your are trying to add the object. - This is just my guess: 
You might try to add
    self._finished_add = True

as in the original code for add() and/or even use 


as in the original code for createAndAdd().

This is what works for me:

    class addView(form.AddForm):

	form_fields = form.Fields(IAdr)

	template = namedtemplate.NamedTemplate('af')

	label=u'Adresse Hinzufügen'

	def setUpWidgets(self, ignore_request=False):
	    super(addView, self).setUpWidgets(ignore_request=ignore_request)

	def create(self, data):
	    a = Adr()
	    for k in data.keys():
		setattr(a, k, data[k])
	    # für nextURL() später
	    return a

	# quasi redirect
	def nextURL(self):
	    return absoluteURL(self.a, self.request)

	# "Speichern"
