Hi Sebastian,

you can use the setUpWidgets hook in your grok.Form.

example:
---------
from zope.formlib.form import setUpWidgets


class AddForm(grokForm):
     ...


     def setUpWidgets(self, ignore_request=False):
         data={'publish_date': date.today()}
         self.adapters = {}
         self.widgets = setUpWidgets(
                          self.form_fields,
                          self.prefix,
                          self.context,
                          self.request,
                          ignore_request=ignore_request,
                          data=data)
