url call:
"/posts/13"

eager_cache([Posts, :show], :store => :action_store)  { self.class.build_request(url(:post, @comment.post), :id => @comment.post.id) } 

Doesn't return any errors, but doesn't cache either

irb(main):014:0> u.update_attributes(:password => "test", :password_confirmation => "test")

Updating password a no go
irb(main):004:0> u.update_attributes(:password => "test", :password_confirmation => "test")
 ~ SELECT `id` FROM `users` WHERE (`login` = 'justin') ORDER BY `id` LIMIT 1
=> true
irb(main):005:0> 

Updating other attributes works fine
irb(main):007:0> u.update_attributes(:city => "test")
 ~ SELECT `id` FROM `users` WHERE (`login` = 'justin') ORDER BY `id` LIMIT 1
 ~ UPDATE `users` SET `city` = 'test', `updated_at` = '2008-11-21 11:06:40' WHERE (`id` = 1)

Problem: With a form_for in Rails 3, it checks object.errors['field'].any? 
which in DataMapper returns nil if no errors are found, 
in ActiveRecord it returns an empty array.

<% form_for @user, :url => "/users" do |f| %>
  <%= f.text_field :login %>
<% end %>

You have a nil object when you didn't expect it!
You might have expected an instance of Array.
