I just installed rails 1.2.1 and am having trouble starting my  
application when I define a singleton resource. It loads up fine with  
all my normal map.resources, but when I use map.resource, I get an  
error.

For example, if I add this to routes.rb

map.resource :account

I get the following error:

/usr/local/lib/ruby/gems/1.8/gems/actionpack-1.13.1/lib/action\_controller/routing.rb:936:in  
`build': undefined method`[]’ for :account:Symbol (NoMethodError)

Is a singleton resource supported in rails 1.2.1?

Thanks

Nope, it went in after the feature freeze.
