Problem with ajax validation tutorial

Rails
1

Hi,

I’d like to make an ajax form validation, like this :
http://www.davidjrice.co.uk/files/ajax_validation.mov

But the problem is that there is a tutorial that isn’t working fine (at
al:s) : http://www.davidjrice.co.uk/articles/20 … y-on-rails

Can someone find this problem? Or do you know a nice tutorial with the
same result?

Thanks a lot
