大澤と申します。
数時間調べているのですが、行き詰ってしまいました。
テスト用のコードもGITHUBにあげておきました、
どなたか力を貸していただければと思い、メールしています。

■やりたいこと
１．/users/:id/activate　という型のURL
２．:idには、ピリオドを含む可能性がある。

■現在のconfig/routesファイル
--------------------------------------------------------
  map.resources :users, :member => { :activate => :any },
:requirements => { :id => /.*/}
--------------------------------------------------------

■現在の動作
/users/a/edit              #OK
/users/a/activate        #OK
/users/a.aa/edit         #OK
/users/a.aa/activate   #NG

map.resourcesにmemberで追加したメソッドを、params[:id]にピリオドを含むデータをリクエストした場合、
Routing Errorが発生する。（showメソッドがある場合はshowが呼ばれ、params[:id]に以降が入る。）
No route matches "/users/a.aa/activate" with {:method=>:get}
（ログは一番下につけておきます）

ぐぐって見たところ、:requirements => { :id => /.*/}でうまくいった人をみつけたのですが、うまくいかず、
:requirements => { :id => %r([^/;,?]+) } というのも見つけたのですが、
これでも、だめでした。

どうも、:requirements => { :id => /.*/}を設定すると、a.aa/activateの部分すべてがparams[id]に設定されて
いるようで、自分で正規表現を書いてみたのですが、結局うまくいきませんでした。（あまり自信なし）
{ :id => /[a-zA-Z0-9.]*/}


■環境は
ruby -v
ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32]

rails -v
Rails 2.2.2

Windows XP SP3

■テストコード
以下に公開しています。
