    Iterating through an IPublishedContent collection

    Converting a previously working menu to strongly typed in V7.2.2

    var home = Model.Content.AncestorOrSelf();
    var pageCollection = home.Children;

    var topPages = pageCollection.Where(x => x.IsVisible() && x.GetPropertyValue<bool>("showInTopMenu"));

    @foreach (var page in topPages) { <------Fails, says previous line is NullReferenceException

    I suspect I can't just "foreach" through it, but can't find reliable info :(

    If I put topPages out to the page I get 

    System.Linq.Enumerable+WhereEnumerableIterator`1[Umbraco.Core.Models.IPublishedContent]

    Any clues or links appreciated.

    Yes, you can as its a enumerable. I'm assuming you expect topPages to not be empty?

    Could post the whole code and the whole error?
