Actionerrors In Controller Base Class In Components

I am new to Yii and I want to know how I can reference my error handler action in my config/main.php file if I will place it inside the Controller base class found inside the components folder whereas the common implementation is this:


'errorHandler'=>array(

            'errorAction'=>'site/error',

        ),

I want to know what is the correct value for the ‘errorAction’=> when actionErrors is placed in the base controller.

Any help?
