I recently upgrade to rails 2.1.1 from rails 1.2.3. When I create a  
form, it generates this error when the form is displayed:

undefined method `protect\_against\_forgery?’ for #\<ActionView::Base:  
0x30cbd9c\>

Extracted source (around line #5):

I know protect\_against\_forgery? is defined in  
ActionController::RequestForgeryProtection, but no where I can find it  
is defined as a helper.

It is called from /usr/local/lib/ruby/gems/1.8/gems/actionpack-2.1.1/  
lib/action\_view/helpers/form\_tag\_helper.rb so I assume that this  
should be available to all views. Maybe I didn’t loaded something  
correctly?

Help is much appreciated!
