[Zope3-Users] formlib confusion

[Alen Stanisic]

Hi Pete,

I assign templates in view classes when using formlib:

from zope.app.pagetemplate.viewpagetemplatefile import
ViewPageTemplateFile
class ConsumerRegistrarForm(form.Form):
    .
    .
    template = ViewPageTemplateFile('registrar.zpt')
    .
    .

I would also be interested to find out if zcml template directive could
still be used with formlib forms.
