Apply A Default Aftersave Behavior

Hi everyone,

which component/class should I extend/override to apply a default afterSave behavior like Yii:log() to it ?

I've created a file into components folder like Testing.php and extend the CActiveRecord class but it doens't seem to have any effect:

class Testing extends CActiveRecord {
	
	protected function afterSave() {
		parent::afterSave();
		echo "Hi";
		exit();
	}
	
}

And I'm already importing it by default:

'import' => array(
        'application.models.*',
        'application.components.*',
...

Some tips about what am I missing ?
