app/views/layouts/application.rhtml:

\<?xml version="1.0"?\> \<%= title %\> \<%= javascript\_include\_tag "prototype" %\> \<%= stylesheet\_link\_tag "application.css" %\> \<%= stylesheet\_link\_tag "#{controller.controller\_path}.css" %\>

app/controllers/login\_controller.rb: class LoginController \< ApplicationController def sidepane do\_login params[:login] if request.post? render :partial =\> 'layouts/sidepane' end

def logout  
session[:user\_id] = “”  
redirect\_to “/”  
end

def do\_login login  
if request.post?  
# I’m add password checking later  
session[:user\_id] = User.find(login[:id])  
end  
end

private :do\_login  
end

If I try to login it deletes div#main (firebug said it as well) and do  
not update div#sidepane. What’s wrong?
