Rails - Feb 2008 - TypeError in highlight (ActionView::Helpers::TextHelper)

I was trying to highlight more than 1 term in a text with highlight
method from TextHelper. Much to my surprise, I just copied the example
from Rdoc (http://api.rubyonrails.org/classes/ActionView/Helpers/
TextHelper.html#M001050):  highlight(''You searched for:
rails'',
[''for'', ''rails''],
''<em>\1</em>'')

But I get TypeError.

C:/ruby/lib/ruby/gems/1.8/gems/actionpack-1.13.6/lib/action_view/
helpers/text_helper.rb:48:in `escape''
C:/ruby/lib/ruby/gems/1.8/gems/actionpack-1.13.6/lib/action_view/
helpers/text_helper.rb:48:in `highlight''

Then I updated to Rails 2.0.2 (gem update rails -y ). But still
doesn''t work. On the two lines above, the path
is ...actionpack-1.13.6 ... what do I need to do to work with
actionpack 2.0.2?

I''m working with netbeans for win XP

Thanks in advance,

Paulo Pereira

You''re environment.rb probably says something like
RAILS_GEM_VERSION = ''1.2.5'' unless defined? RAILS_GEM_VERSION

Change that to the version of rails you want to use. Don''t forget to  
run rake rails:update
