[Zope3-Users] Maintaining data fields on form edit

[mats.nordgren]

This seems to work

class EditForm(form.EditForm):
  form_fields = form.Fields(ISchema)

  def __init__(self, context, request):
    self.context, self.request = context, request

  @form.action('Edit')
  def handle_edit_action(self, action, data):
    if data['image'] != None:
      self.context.image = data['image']
    # continue adding values to context for other fields


Cheers,

Mats
