Rails - Dec 2006 - reset_session Clears Flash Contents Before Method Exits

Hello,

In the code below, if reset_session is called in action index, 
flash[:test] is not passed to action special. I would expect that 
calling  reset_session would clear anything in the session/flash which 
was set before reset_session was called but to have no impact on the 
storage of anything in the session/flash after it reset_session was called.

Interesting..."p flash" in action index reveals that the flash stores 
appropriate contents after reset_session is called. The clearing of the 
flash occurs during the redirect.

Is this a bug?

Thank you,
Ben Gribaudo

=========Example Code
=========class TestController < ActionController::Base
    def index
        ## comment this "reset_session" call and flash contents are 
passed to action special
        reset_session
        flash[:test] = ''This should be passed to action
special.''
        redirect_to :action => ''special''
        ## this outputs (to console) the expected contents of the flash
        p flash
    end
   
    def special
        unless flash[:test]
            render :text => "Flash contents cleared."
        else
            render :text => "Flash contents maintained."
        end
    end
end

=========Test which should pass if flash contents are maintained. Won''t
pass if
reset_session is called in action index.
=========require ''test/test_helper''
require ''application''
require ''test''

class TestTest < Test::Unit::TestCase
  def setup
    @controller = TestController.new
    @request    = ActionController::TestRequest.new
    @response   = ActionController::TestResponse.new
  end

  def test_ensure_flash_passed
    get :index
    assert_equal ''This should be passed to action special.'',
flash[:test]
    assert_redirected_to :action => ''special''
  end
end
