I was working off the comments in the FormBuilder class. The 'hook' methods that you mention above, how are they supposed to be accessed - I don't understand from what is written down - how everything fits together when auto generating a form from a DataObject? Standard forms work fine, and I can set the form header, but I don't understand where I should be creating the above mentioned methods.. Hence why I'd love to see a real world example if anybody has one knocking around?
