REST: Did ActiveResource code broken ? Can't handle Resource.find(:all)...

Hi to all,

I just started with REST development, I created a very simple scaffold_resource and a client app to test it.

All verbs works well but not list !!!

Here what I give when call Airport.find(:all)

./activeresource/lib/active_resource/base.rb:465:in `instantiate_collection': undefined method `collect!' for #<Hash:0xb7b90ac0> (NoMethodError)
        from ./activeresource/lib/active_resource/base.rb:442:in `find_every'
        from ./activeresource/lib/active_resource/base.rb:385:in `find'
        from client.rb:10:in `show_airports'
        from client.rb:16

Did ActiveResource code broken ?

Here what I've generated with scaffold_resource:

ruby script/generate scaffold_resource airport name:string
rake db:migrate

And here my (very simple) client.rb source:

require 'activesupport/lib/active_support'
require 'activeresource/lib/active_resource'

# Define a model for the objects exposed by the site
class Airport < ActiveResource::Base
  self.site = ‘http://localhost:3000/
end

def show_airports
  airports = Airport.find(:all)
  puts "I retrieved #{airports.size} airports !"
end

new_airport = Airport.new(:name => "New airport")
new_airport.save
show_airports

Someone can help me ?

Thanks in advance...
