def handle_render_error(view, e) #:nodoc:
  if e.is_a?(::ActionView::Template::Error)
    e.sub_template_of(self)
    raise e
  else
    assigns  = view.respond_to?(:assigns) ? view.assigns : {}
    template = self

    # Here's the patch: if the javascript runtime throws an error
    # during compilation, we get to this handler but our view 
    # doesn't have a lookup_context - thus throwing a very hard
    # to debug error in Template#refresh. To circumvent, ensure the
    # view responds to lookup_context before refreshing.
    if view.respond_to?(:lookup_context) and template.source.nil?
      template = refresh(view)
      template.encode!
    end
    if ::ActionView::Template::Error.instance_method(:initialize).arity == 3
      # Rails < 4.0 expects three arguments here
      raise ::ActionView::Template::Error.new(template, assigns, e)
    elsif ::ActionView::Template::Error.instance_method(:initialize).arity == 2

      # try and fail graciously if this changes in the future
