base\Controller afterAction()

This method is invoked right after an action is executed.

The method will trigger the EVENT_AFTER_ACTION event. The return value of the method will be used as the action return value.

If you override this method, your code should look like the following:

public function afterAction($action, $result)
{
    $result = parent::afterAction($action, $result);
    // your custom code here
    return $result;
}
