Hi, If you was using Facebooker plugin and Jquery on your project, maybe you will have problem implement it cause Facebooker was come with prototype js default. Here I show how to use Facebooker along with Jquery :

• open file vendor/plugins/facebooker/lib/facebooker/rails/helpers/fb_connect.rb, then edit it.
• search for line that contains

 options = {:js => :prototype, :app_settings => '{}'} 

• change

:js => prototype

• into

:js => jquery

• save file

Now you are ready to use facebooker with jquery. Thanks,
