    The reason you're getting a null reference using Model.Content.Children<Projekt>() is because you're trying to return the children for the current page, instead of returning all of the children of the Projekt document type.

    If the current page doesn't have any children of type 'projekter', then you'll always return a null value.

    Adapting your original solution (that works), you could try using the following line instead:

    var blogItems = Model.Content.Site().FirstChild("projekter").Children();
    

    It's a bit shorter and removes the additional logic that you're working solution has, so hopefully a happy medium!

    You might also want to look at the documentation on querying as well :)
