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:  
ActionController::UnknownAction (No action responded to 22. Actions:  
edit, index, and update):. 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??

No of course, development and productions are different servers.

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

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