Subject: strange: 'super' is not the parent class

When I try to run the attached code (ar2.rb) with ruby 1.8.2 I get the
following error:

../ar2.rb:41:in `packDecl': undefined method `packDecl' for
"\000\000\000\005\000\000\000\002":String (NoMethodError)
        from ./ar2.rb:27:in `pack'
        from ./ar2.rb:54
        from ./ar2.rb:49:in `each'
        from ./ar2.rb:49

It seems like "\0\0\0\5\0\0\0\2".packDecl is called instead of
super.packDecl. Did I overwrite 'super'? Where?



#!/usr/bin/env ruby
require 'pp'

BASE_INFO = 0x2

class StreamData
	attr_accessor :typeDataLength
	attr_accessor :type
	
	attr_accessor :payloadLength
	
	def initialize
		@typeDataLength = 0
		@payloadLength = 0
	end
	
	def packDecl
		length = @typeDataLength + @payloadLength
		return [length, @type].pack("LI")
	end
	
	def packTypeData
		return Array.new
	end
	
	def pack
		return packDecl + packTypeData
	end
end

class BaseInfoData < StreamData 
	attr_accessor :name

	def initialize
		super
		@type = BASE_INFO
	end
	
	def packDecl
		@typeDataLength = [@name].pack("a*").length
		return super.packDecl
	end
	
	def packTypeData
		return [@name].pack("a*")
	end
end

["happy", "two"].each { |file|
	
	baseInfo = BaseInfoData.new()
	baseInfo.name = file
	
	pp baseInfo.pack
}
