I've tried using jQuery's .submit() method, but it doesn't work.
I suspect I need to modify the way that this line behaves in my form code:
return new Form($this, 'QuoteForm', $fields, $actions);
adding in a 5th parameter where validation normally fits, but again I'm stuck trying to figure out how to specify my own validation function.
Can anyone help, or should I post a more thorough example?
