Yii CAPTCHA url is broken

Question

I want to create an AJAX-registration form on my Yii-project. So on every page I have a login-button, which shows a popup if the user isn\'t authorized. In that popup he can see

Answer 1

So, while I was waiting for help, I solved the problem by myself :) In my project i separated my controllers into the next hierarchy:

/frontend
/backend

All controllers for common users are (of course) in Frontend section, including UserController and MainController.

Yes, I wrote some configs to hide /frontend/ in URL's like this:

'/' => 'frontend//',

And i was sure, that string in my CAPTCHA config ('captchaAction' => '/user/captcha') knows where to go (and it was almost so!), but NO!

I should write FULL PATH to my controller and action like below:

'captchaAction' => '/frontend/main/captcha',

As I said in question, I placed my CAPTCHA action in UserController, but now you can see it is located in MainController (i deleted it from UserController)

And I got an error:

CCaptchaValidator.action "captcha" is invalid. Unable to find such an action in the current controller. 

So, to solve this, I just had to use a property captchaAction of CCaptchaValidator in my User MODEL! Code:

array('code', 'captcha', 'captchaAction'=>'/frontend/main/captcha', 'allowEmpty'=>!Yii::app()->user->isGuest)

So, now my AJAX Captcha validation works correctly where I want.

Good luck with Yii's default CAPTCHA, dear community!
