Can't disable ajax validation

My form starts like this:

 <?php $form=$this->beginWidget('CActiveForm', array(




    )); ?>

but it still sending form contents via ajax and being validated (i.e. ajax validation).

How do I turn it off? I don’t want it because I have an issue with CAPTCHA. Now I don’t want to resolve Captcha issue while ajax validation is on, I just want to turn off ajax validation.

I resolved it. The problem was that I had two forms with the same id. Shame on me ))
