I’ve been playing around with the Premier League Fantasy Football API in the evenings recently and came across a problem with their API.

The Problem The user is part way through completing a form or wizard and then the accidently click a link or trigger back on their browser… 😞 Their progress is lost and you have a frustrated user on you hands.

Often in real world applications you’ll find yourself needing to set up conditional validation rules. e.g. Require this if that === “foo”.
