title: Virtual field in 'fields' find condition - Cakephp
body: <p>I have a Student model with a virtual field:</p>
  
  <pre><code>    var $virtualFields = array(
      'full_name' =&gt; 'CONCAT(Student.fname, " ", Student.lname)'
  );
  </code></pre>
  
  <p>I am doing a find operation to fetch specific fields using 'fields':</p>
  
  <pre><code>$this-&gt;Student-&gt;find('all', array('fields' =&gt; array('Student.fname','Student.lname')));
  </code></pre>
  
  <p>For some reason, the virtual field is not being created after finding the records. I tried adding <code>Student.full_name</code> but of course it gives an <code>unknown column</code> error in mysql.</p>
  
  <p>Any ideas?</p>
