Bug #1140: Parsing error gives method_missing a nonexistant method name
http://redmine.ruby-lang.org/issues/show/1140

Author: Ben Rayfield
Status: Open, Priority: Normal
Target version: Ruby 1.8.6
ruby -v: ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32]

This does not happen consistently but I have seen it about 5 times.

My operating system is Windows Server 2003 SP2.

my code: def method_missing method_name, *params

method_name.inspect is :backgroundColor=

Maybe I dont understand how method names are represented, but I thought the method name should be "backgroundColor" or "=" but not the concat of both.

Parsing fails in element.rb, which I attached:

def highlight(set_or_clear)
  if set_or_clear == :set
    begin
      @original_color ||= style.backgroundColor
      style.backgroundColor = @container.activeObjectHighLightColor
    rescue
      @original_color = nil
    end
  else # BUG: assumes is :clear, but could actually be anything
    begin
      style.backgroundColor = @original_color unless @original_color == nil
    rescue
      # we could be here for a number of reasons...
      # e.g. page may have reloaded and the reference is no longer valid
    ensure
      @original_color = nil
    end
  end
end

...my code...:238:in `method_missing'
c:/ruby/rubyinstalled/lib/ruby/gems/1.8/gems/watir-1.5.3/./watir/element.rb:194:
in `highlight'
c:/ruby/rubyinstalled/lib/ruby/gems/1.8/gems/watir-1.5.3/./watir/element.rb:227:
