Wierd session behavious in development mode after switching

Rails
1

class UserController < ApplicationController
def home
# Following line throws error and session[:user] set by previous
action login is gone here.
$logme.info “Home session information: is #{session[:user].login}
and #{session[:user].firstname}”
redirect_to_stored_or_default :controller => “start”,:action =>
‘index’
end

trying to access also called from a Ajax request normally. If not,

they will be sent to “/user/home”.
def login
if session[:user]
render :partial => ‘shared/error_msg’, :object => “Invalid
Request”, :layout => true
return
end

return if generate_blank

if @user = User.authenticate(params[:user][:login],

params[:user][:password])
@user.logged_in_at = Time.now

  session[:maps_cust_pref] = nil
  save_option = params[:save_option][:save_option].to_i

  generate_cookie_for_ticks

  save_pref if save_option == 1
  session[:user] = @user
  session[:user].save

  # printing session information works here, but as soon as we

redirect_to another page, all the session
# information is lost
$logme.info “From session information: is #{session[:user].login}
and #{session[:user].firstname}”
render :update do |page|
page.redirect_to(:controller => ‘user’,:action => ‘home’)
end

else
  render :update do |page|
    page.replace_html('errordiv',:partial => 'error',
                      :object => "<p

style=‘background:#d57068;margin:0px 200px 2px 0px; padding:2px 5px 2px
5px; color:#ffffff;’>Invalid Login ID or Password

")
page.visual_effect :highlight, ‘errordiv’
end
end
end
end

I am doing nothing special here and yet i wonder why this happens?

It was working alright on 1.1.6 although.

Well in case, anyone is looking for exact error its here:
You have a nil object when you didn’t expect it!
The error occurred while evaluating nil.login
