Rails - Nov 2005 - undefined method `protocol' for nil:NilClass

Hi! This may have been answered somewhere before, but my searches turned 
up nothing.

I am developing a Rails app that generally works, but just generated a 
new controller ("list" controller), did not add anything, and when I
go to
      http://localhost:3000/list/
I receive an error. It appears that the page was properly generated, but 
somewhere preparing the result raised this exception

      undefined method `protocol'' for nil:NilClass

(The protocol method returns either http: or https:)  I have other 
controllers that work fine, but I''ve been stumped with this one. I am 
pasting the error page and development log below. Versions are in the trace.

Does anyone know the cause, or have an idea/hint/solution for this? :-)

Thanks!
Allen

It looks like the request method for your controller is returning nil  
instead of a request instance. Make sure that you don''t assign  
anything to @request, and also ensure that you haven''t redefined  
request.

Thanks for the suggestion. However, this is happening on a 
newly-generated controller, with empty method definition and default 
view template. I have added no code yet. :-( Other controllers work 
fine. I will hunt further.
