The base class provides two things:
- the implementation of the edit action, and
- the "registration" of the edit action in self.actions.

Well, the entire set of actions is replaced.

Interesting.

That might be; I'll let Jim say for sure.
If you only want to add actions, what you can do in your view class is this:
class MyForm(form.EditForm):
actions = form.EditForm.actions[:]
@form.action(_("Whatever"))
def handle_whatever(self, action, data):
pass
