We have a master / detail document type similar to blog & posts and we need the posts to be filtered according to some filters chosen by the users. This required an ajax request to be send to a action in the controller to return the partial view and update the HTML element with the filtered result. As I have understood, these custom actions need to be inside a surface controller to be found in the routing system. This is working well, however, inside the action, the response of the IPublishedContent model = Umbraco.Content(id) is null while the same has results in another macro.

I was just wondering if there's another best practice for this situation or how this null result can be solved.
