I’m having a problem with acts\_as\_list, and I’m stumped. I have two  
models: page and item. A page contains a list of items:

class Page \< ActiveRecord::Base  
has\_many :items, :dependent =\> :destroy, :order =\> :position  
belongs\_to :portfolio  
…

class Item \< ActiveRecord::Base  
belongs\_to :page  
acts\_as\_list :scope =\> :page  
…

When I try to destroy an item, I get this error:

NoMethodError in ItemsController#destroy  
undefined method `updated?’ for #Page:0x26eeedc

If I remove the :dependent =\> :destroy in the has\_many declaration,  
everything works fine (the item’s page\_id is nulled, but the item  
isn’t destroyed). Any idea what I’m doing wrong? I’ve Googled til my  
fingers bled, but no luck. Any help is greatly appreciated!
