I am extending my application to provide output in either html or xml  
for most actions. Following the guidance of the default routes.rb I  
modified my index route from:

map.index ‘/index/:action’,  
:controller =\> ‘index’,  
:action =\> ‘show’

which works fine to

map.index ‘/index/:action.:format’,  
:controller =\> ‘index’,  
:action =\> ‘show’,  
:format =\> nil

which fails with “No action responded to index” (no changes to  
controller code, and its the first route in routes.rb). I guess that  
the routes architecture is changing quite a bit, but i am not on edge  
rails, I’m on 1.2.3.7116 (I think the latest gem version).

What is the right rails approach to route construction for this? And  
where have i messed up on the above?

Cheers, and thanks, --Kip
