title: yii ajax validation errors show up
body: <p>I have the following form:</p>
  
  <pre><code>$form = $this-&gt;beginWidget('bootstrap.widgets.TbActiveForm', array(
              'id'=&gt;'new-agenda-entry',
              'enableAjaxValidation'=&gt;true,
              'action'=&gt;'')); ?&gt;
          &lt;div class="four columns"&gt;
              &lt;div class="right top5 sufix10"&gt;
                  &lt;?php echo $form-&gt;labelEx($model,'eventTime'); ?&gt;
                  &lt;?php $this-&gt;widget('zii.widgets.jui.CJuiDatePicker', array(
                  'name'=&gt;'UserAgenda[eventTime]',
                  'model'=&gt;$model,
                  'options'=&gt;array(
                      'dateFormat'=&gt;'yy-mm-dd',
                      'minDate'=&gt;'new Date()',
                  ) // jquery plugin options
              ));?&gt;
              &lt;?php echo $form-&gt;error($model, 'eventTime'); ?&gt;
              &lt;/div&gt;
              &lt;div class="right top5 sufix10"&gt;
                  &lt;?php echo CHtml::dropdownList('eventTime_hour', false, $this-&gt;getHourArray()); ?&gt;
                  &lt;?php echo CHtml::dropdownList('eventTime_min', false, array('00'=&gt;'00', '30'=&gt;'30')); ?&gt;
              &lt;/div&gt;
          &lt;?php echo $form-&gt;labelEx($model,'note'); ?&gt;
          &lt;?php echo $form-&gt;textField($model, 'note');?&gt;
          &lt;?php echo $form-&gt;error($model, 'note'); ?&gt;
  </code></pre>
  
  <p>The model is successfully validated on the server as I can see the response in Firebug:</p>
  
  <pre><code>{"UserAgenda_eventTime":["Event time cannot be blank."],"UserAgenda_note":["Note cannot be blank."]}
  </code></pre>
  
  <p>The message seems fine, so does the html but the hidden inputs generated by yii remain hidden and empty.</p>
