I follow the instruction :
http://wiki.rubyonrails.org/rails/pages/How+to+use+text_field_with_auto_complete
but failed
My Firebug said
http://localhost:3001/users/auto_complete_for_language_name422
(360ms) prototype.js (line 1222)
I dont know why?
My Rails is 2.0
Window XP
Firefox 2.0
Thanks
Best regard,
