title: Cant do work Propel Match validators
body: <p>Im developing a CRUD application. I use Propel as ORM, and added validate rules into the schema.xml. But this, not work fine.
  For example, i send a string that contains a user lastname, and the validator is:</p>
  
  <pre><code>&lt;rule name='minLength' value='4'/&gt;
  &lt;rule name='maxLength' value='30'/&gt;
  &lt;rule name='notMatch' value='/^\s+$/' /&gt;
  &lt;!-- the name can be only chars and spaces --&gt;
  &lt;rule name='match' value='/[^A-Za-z ]$/'/&gt;
  </code></pre>
  
  <p>The user lastname sent was: 'Martinez D Elia'. And the valid fails on 4th rule.
  Any idea ?.</p>
