title: has any one gotten acts_as_list to work on rails 3?
body: <p>I installed by putting the following line in Gemfile and 'bundle install':  </p>
  
  <pre><code>gem 'acts_as_list', '&gt;= 0.1.0'  
  </code></pre>
  
  <p>However, when I try to use it, the results are not as expected:  </p>
  
  <pre><code>technician.move_to_top #works =&gt; position = 1  
  technician.move_to_bottom #does not work properly; also makes position = 1  
  technician.move_higher #does not work; returns nil  
  technician.move_lower #does not work; also returns nil  
  </code></pre>
  
  <p>Does this plugin just doesn't work with rails 3 or am I missing a step?  </p>
  
  <p>here is the code I'm using:  </p>
  
  <pre><code>class WorkQueue &lt; ActiveRecord::Base  
    has_many :technicians, :order =&gt; "position"  
  end  
  
  class Technician &lt; ActiveRecord::Base  
    belongs_to :work_queue  
    acts_as_list :scope =&gt; "work_queue_id" #I also tried using work_queue  
  end  
  </code></pre>
  
  <p>this is the console:  </p>
  
  <pre><code>wq = WorkQueue.new  
  technician = Technician.last
  wq.technicians &lt;&lt; technician  
  </code></pre>
