Set the layout file for error action dynamically

Question

I know there are different ways to choose layout file. It can be done

• in the configuration
• with Yii::$app->layout = \'...\'
• with

Answer 1

One way could be to set the the layout file for the application in beforeAction in each controller:

public function beforeAction($action) {
    Yii::$app->layout = $this->layout;
    return parent::beforeAction($action);
}

It could be optimized by putting this in an extra controller from which all other controllers inherit.

But I don't really like this solution. Seems to me like a workaround. Also this does not work if the SiteController defines a layout by itself (as $layout property or within a method).
