Hi, I cannot, at first sight, add values to REQUEST.form dictionnary this way : <dtml-call "REQUEST.form.set ('Var', 'Value')"> Zope returns a key error on "set". The same appends for 'append' method, as if, in fact, REQUEST.form was not a dictionnary. Does anyone know why and how to bypass this ?... Regards, Pierre-Julien Grizel
