I see...   Seems to be OK for what you're wanting to do.

OK, but for EditForm you need an object the fields of the form 
can be bound to. If that's not a content object it could just be 
an adapter.

Another and probably better way in this case would be not to 
derive from EditForm but from Form.

I just have to solve a similar problem and got it working the 
following way (IPersonRegistration is the schema for the form, 
INode is the interface of something like your Centershock 
object):

browser/configure.zcml:

  <browser:page 
      name="registration.html"
      for="..interfaces.INode"
      class=".registration.PersonRegistrationView"
      permission="zope.Public" />


browser/registration.py:

from zope.formlib.form import Form, FormFields, action
from zope.formlib.i18n import _

class PersonRegistrationView(EditForm):

    form_fields = FormFields(IPersonRegistration)

    @action(_("Apply"))
    def handle_edit_action(self, action, data):
        print data # here we'll do the real stuff...

        
As often with Zope 3: simple but not easy (to find out) ;-)
