RubyAmf and Rails 3 - ruby-on-rails

Question

I have recently been trying to upgrade my app form Rails 2.3.8 to newly-releases Rails 3.
After going through fixing some Rails 3 RubyAMF doesn't seem to work:
>>>>>>>> RubyAMF >>>>>>>>> #<RubyAMF::Actions::PrepareAction:0x1649924> took: 0.00017 secs
The action '#<ActionDispatch::Request:0x15c0cf0>' could not be found for DaysController
/Users/tammam56/.rvm/gems/ruby-1.9.2-p0/gems/actionpack-3.0.0/lib/abstract_controller/base.rb:114:in `process'
/Users/tammam56/.rvm/gems/ruby-1.9.2-p0/gems/actionpack-3.0.0/lib/abstract_controller/rendering.rb:40:in `process'
It doesn't seem to be able to find the proper controller. Might have to do with new changes in Rails 3 Router. Do you know how to go about finding the root cause of the problem and/or trying to fix it?
I'm pasting code from RubyAMF where this is happening (Exception happens at the line: #service.process(req, res)):
#invoke the service call
def invoke
begin
# RequestStore.available_services[#amfbody.service_class_name] ||=
#service = #amfbody.service_class_name.constantize.new #handle on service
rescue Exception => e
puts e.message
puts e.backtrace
raise RUBYAMFException.new(RUBYAMFException.UNDEFINED_OBJECT_REFERENCE_ERROR, "There was an error loading the service class #{#amfbody.service_class_name}")
end

end
end
# put them by default into the parameter hash if they opt for it

begin

result = RequestStore.render_amf_results
#handle FaultObjects
if result.class.to_s == 'FaultObject' #catch returned FaultObjects - use this check so we don't have to include the fault object module
e = RUBYAMFException.new(result['code'], result['message'])
e.payload = result['payload']
raise e
end
#amf3
#amfbody.results = result
if #amfbody.special_handling == 'RemotingMessage'
#wrapper = generate_acknowledge_object(#amfbody.get_meta('messageId'), #amfbody.get_meta('clientId'))
#wrapper["body"] = result
#amfbody.results = #wrapper
end
#amfbody.success! #set the success response uri flag (/onResult)
end

Answer 1

The best suggestion is to try rails3-amf. It currently is severely lacking in features in comparison to RubyAMF, but it does work and I'm adding new features as soon as they are requested or I have time.
