Rails - Aug 2009 - ActionController::UnknownAction (No action responded to 22.

I try to switch my application from Rails 2.2.2 to Rails 2.3.3.

In namespace :admin I have a resource-based controller. See controller
class Admin::OSystemsController < Admin::BaseController
  def index
.......
  end

  def edit
.........
  end

  def update
..........
  end
end

Resource is added to routes.rb like
map.namespace :admin do |admin|
............
    admin.resources :o_systems, :only => [:index, :edit, :update]
............
end

I go to edit page (see view)
.........
<% form_for([:admin, @o_system]) do |f| %>
  <%= f.error_messages %>
  .............
<% end %>

I press submit and exception is thrown:
[b]ActionController::UnknownAction (No action responded to 22. Actions:
edit, index, and update):[/b]. Here "22" is the id of the object.

Everything works properly in development, error is only in production
environment and only ONE time. If I submit form second time then
everything goes well.

Please, help.

Sounds like a stale session issue, are you clearing your sessions out 
when you deploy to production??

clear your memcached sessions prior to deployment to production.. 
development and production are using the same memcache?

No of course, development and productions are different servers.

I restarted memcached to clear sessions and then restarted mongrel. 
Problem still exists.
