CaptchaValidator should be used together with CaptchaAction.
Note that once CAPTCHA validation succeeds, a new CAPTCHA will be generated automatically. As a result,
CAPTCHA validation should not be used in AJAX validation mode because it may fail the validation
even if a user enters the same code as shown in the CAPTCHA image which is actually different from the latest CAPTCHA code.
