Howdy!

In order to correct mistakes in a form I need to override parameters in
REQUEST.form. E.g. a user types a wrong text in a field and I want to
clear it prior to further processing. I tried (in an external method)
self.REQUEST.set('whatever','') but this doesn't work (Zope 2.2.4).
What can I do?
