Rails Ruby on Rails

I am not sure that it is a bug in Rails 3 or not.

I just came back to Rails after a long break and I was refreshing my memory about before_filter.

In Rails book and Google results I read return false in before_filter should stop the chain and prevents action running.

class ClubsController < ApplicationController                                                                                                                                                                                                
  before_filter :test

Log output for this:

Started GET "/clubs" for 127.0.0.1 at 2010-09-17 02:28:25 +0200
  Processing by ClubsController#index as HTML
--- *** filter *** ---
Rendered text template (0.0ms)
Completed 200 OK in 13ms (Views: 13.0ms | ActiveRecord: 0.0ms)

Which is fine.

Now I remove the render text: line from the filter method.

  protected
  def test
    logger.info '--- *** filter *** ---'
    #render text: 'text'
    return false
  end

The log putput will look like:

Started GET "/clubs" for 127.0.0.1 at 2010-09-17 02:27:23 +0200
  Processing by ClubsController#index as HTML

Rendered clubs/index.html.erb within layouts/application (3.0ms)
Completed 200 OK in 17ms (Views: 6.0ms | ActiveRecord: 0.0ms)

As you see 'return false' simply didn't stop the action. Is this a rails bug or a new feature in Rails 3?

I am using Gentoo, rvm, ruby 1.9.2, rails 3.0.0, development env.
