I'm not sure that it is.
In this case, the callback is defined in the config file - which is
loaded before the cat-controller calls process():

    validators:
      - type: Callback
        callback: "MyApp::Controller::Submissions::user_validator"

Dermot, can you post the code where you're actually using the form?
(for example, the cat-controller action method)
