    Using HasValue() with AncestorOrSelf() in MacroPartial

    Should be pretty self-explanatory of what I'm trying to do, but I'm getting definition not present [on HasValue] exception.  Could someone help me out to what the line "should" be.  Here's my last incarnation of trying different things:

    var pageWithAds = CurrentPage.AncestorOrSelf((Func<dynamic, bool>)(p => p.HasValue("rotationAds"))).FirstOrDefault();

    I would go for the the strong typed version of this.

    var pagesWithAds = Model.Content.AncestorsOrSelf().FirstOrDefault(p => p.HasValue("rotationAds"));

    Im pretty sure that will give you what you want. It will return an IPublishedContent Item rather than Dynamic

    Thanks, Peter.  That did it and having typed is a bonus.  Here's my final code (unless someone sees a flaw):

        var pageWithAds = Model.Content.AncestorsOrSelf().FirstOrDefault(p => p.HasValue("rotationAds"));
    var rotationAds = ((pageWithAds != null) ? pageWithAds.GetPropertyValue<string>("rotationAds") : string.Empty);
    var ads = Umbraco.Media(rotationAds.Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries));
    var adsPicked = (ads.Count() > 3) ? ads.Random(3) : ads;
