title: fluent validation collection items not null/empty
body: <p>Im using fluent validation with mvc4</p>
  
  <p>In my Model I have a list:</p>
  
  <pre><code>public List&lt;int&gt; TransDrops { get; set; } 
  </code></pre>
  
  <p>in the view im creating text boxes for each item in the list.</p>
