About issue of Route Globbing in rails 3.0.9

HI

I have the issue about the route globbing in rails 3.0.9.

here is the code:

in the AccountsController:
def show2
     @account = Account.first(:conditions => ['login = ? AND enabled = ?', params[:account], true])
end

config/routes.rb
   match "/my/*account", :to => "accounts#show2"

rake route showed:
                /my/*account {:controller=>"accounts", :action=>"show2"}

Try to access the http://127.0.0.1:3000/my/test/ and the log/development.log showed:

Started GET "/my/test" for xxx at Tue Jun 27 16:07:14 -0400 2011
   Processing by AccountsController#show2 as HTML
   Account Load (0.6ms) SELECT `accounts`.* FROM `accounts` WHERE (login = NULL AND enabled = 1) LIMIT 1
Completed 404 Not Found in 9ms
Rendered public/404.html (1.6ms)

So the params[:account] was not set by route globbing??

Any help is appreciated.

Kind Regards
