Hobo with authlogic user session problem

Question

Just a day into hobo now I think it's great but got a small problem. User session are running with hobo, can't get current_user. I can login in to my site as normal without adding the line

session[:user] = user.typed_id

def create 
    @user_session = UserSession.new(params[:user_session]) 
    session[:user] = user.typed_id 
    if @user_session.save 
      flash.now[:notice] = "You have logged in!" 
      redirect_to root_url 
    else 
      render :action => 'new' 
    end 
  end

But when I do add this line it causes the login to break. The user guest/admin selector disappears.

What am I doing wrong here? Regards Dan
