Yii client-side validation and jQuery Form plugin integration

I'm using Yii framework in one of my projects and I would like to use the jQuery Form plugin together with Yii client-side built-in validation.

I can't get them work together. If I setup jQuery form plugin with this simple js code:

$('#myform-id').ajaxForm();

the client-side validation is performed but it doesn't stop the form submission even if the validation fails. I suppose that this is related to the fact that both Yii client-side validation library and jQuery form plugin bind the same "submit" event on the form.

FYI, I double checked that there no js errors with FireBug and Chrome console.

I wonder if someone experienced the same issue and solved that someway.

I solved this way:

Yii Active Form init code:

<?php $form = $this->beginWidget('CActiveForm', array(
    'id'=>'user-form',
    'enableClientValidation'=>true,
    'clientOptions' => array(
         'validateOnSubmit'=>true,
         'validateOnChange'=>false,
         'afterValidate'=>'js:submiAjaxForm'
     )
)); ?>

And in the same page I've added this js code to submit the form via jquery form plugin:

function submitAjaxForm(form, data, hasError)
{
   if(!hasError)
   {
       $('#user-form').ajaxSubmit(
       {
           // ajax options here
       });
   }
}
