Rails - Mar 2006 - alias_method interferes ApplicationHelper

Hello,
I''m using Ruby 1.8.4 (darwinport), rails-1.0.0 (gem) , Powerbook / Mac
OS X 10.4.5 , Webrick.
How come Rails always raises NoMethodError for my helper (must_fill and
rp or number_to_currency_rp) in application_helper.rb ?
I doubt that alias_method is the culprit, but if i give #
comment then there will be no errors at all ... :/
what am i doing wrong? is it a bug or stupid me? Thx

------------------
This is my helper:
------------------
module ApplicationHelper
   alias_method :rp, :number_to_currency_rp

	# Rp 1.907.000,00 instead of $1,907,000.00
	def number_to_currency_rp(dolar)
	  number_to_currency(dolar, {:unit => "Rp ", :separator =>
",",
:delimiter => "."})
	end
	
   def must_fill(x)
     ''<span style="color:red;">'' + x +
''</span>''
   end
end

--------------------
 From ri -f bs alias:
---------------------------------------------------- Module#alias_method
      alias_method(new_name, old_name)   => self
------------------------------------------------------------------------
      Makes _new_name_ a new copy of the method _old_name_. This can be
      used to retain access to methods that are overridden.

         module Mod
           alias_method :orig_exit, :exit
           def exit(code=0)
             puts "Exiting with code #{code}"
             orig_exit(code)
           end
         end
         include Mod
         exit(99)

      _produces:_

         Exiting with code 99

You should first define a method and then alias it:

module ApplicationHelper
       # Rp 1.907.000,00 instead of $1,907,000.00
       def number_to_currency_rp(dolar)
         number_to_currency(dolar, {:unit => "Rp ", :separator
=> ",",
:delimiter => "."})
       end
       alias_method :rp, :number_to_currency_rp

end
