I have an MVC widget with Index method that has RelativeRoute attribute, but when calling the route relative to its page, the content is rendered alone and ignored the template/page, which is against what is mentioned in this docs (docs.sitefinity.com/feather-use-the-relative-routes-api)
SiteHeader and SiteFooter placeholders are not rendered!!!
Knowing that I am using pure MVC mode, cshtml layout, and controller's method is:
public ActionResult Index(string param1, string param2, string param3)
