I've been playing around with jqTouch to create a mobile version of my Rails app. I use Devise for authentication, but it won't work with jqtouch. It has something to do with jqtouch's "auto-ajax" functionality. I used a "rel=external" attribute on my sign in form to get it to do something at all (before it simply wouldn't do anythin...

For example, using require or load in my unit test causes the script to execute before the tests execute. I have many of these scripts and I really pref...
