Rails flash: notification not working

Question

I have this code:

def create
  login(params[:email], params[:password])

  if current_user
    flash[:notice] = "Welcome back #{current_user.email}"
    return redirect_to_first_page
  else
    flash[:notice] = "Email or password is wrong. Try again !"
    redirect_to root_url
  end
end

when the login is completed successfully, flash is installed and redirects to the first page. This part works. The second part does not set the flash notification message. Then, when the page is displayed, the flash message is not displayed. What else i try to have

return redirect_to root_url

but still nothing shows. In my controller, I have a helper such as flash_notice, all it does is return flash [: notice]. This is due to the fact that the flash is always empty in the view, but available in the controller. In the view, I have only one line:

<%= flash_notice %>

I use rails 3.1
