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:

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

@param string $actionId the action just executed.
@param mixed  $result the action return result.
@return mixed the processed action result.
This method is invoked right after an action is executed .
