title: Cakephp 2 update multiple records
body: <p>i'm newbie in cakephp and i trying to update multiple rows in one transaction like:</p>
  
  <pre><code>$Model-&gt;saveMany($data, array('deep' =&gt; true));
  </code></pre>
  
  <p>... And the structure of the <strong>$data</strong> array is:</p>
  
  <pre><code>$data = array(
    (int) 1 =&gt; array( 'Item' =&gt; array('id' =&gt; 2, 'name' =&gt; 'Name 1') ),
    (int) 2 =&gt; array( 'Item' =&gt; array('id' =&gt; 3, 'name' =&gt; 'Name 2') ),
  );
  </code></pre>
  
  <p>I Already tried with <strong>saveAll</strong> instruction and without <strong>deep</strong> parameter but nothing :( .... what's wrong?</p>
  
  <p>Thanks for the help :)</p>
