I've followed the instructions here:
http://github.com/plataformatec/devise/wiki/How-to-edit-user-form-without-current-password
But it seems to ignore that and still validate and require current password.
In fact, I can do whatever I want to app/controllers/registrations_controller.rb including putting tonnes of syntax errors in, and it still asks for the current password to be present.
What am I missing?
