the error message suggests, that on one of your checkout steps, your form_fields attribute on that step's view attr is a list, instead of being a zope.formlib.FormFields( ) instance. if you want an empty form_fields, just don't pass args to the FormFields constructor.
looking over your source change browser.checkout.VcsCheckoutPayment.. form_fields = [] to form_fields = form.FormFields() hth, kapil On Fri, Feb 13, 2009 at 3:20 AM, hannesc <[email protected]> wrote: > > I am busy working on a payment processor that overrides the checkout > process.
