    Merchello NullException after github fork

    Using Umbraco And Getting Started
    Umbraco 7

    Hi, After a fresh install of latest version of Merchello (forked from github) I get a NullException when trying to load the FastTrack demo site. The exception occurs in _ProductBox.cshtml:

    Exception Details: System.ArgumentNullException: Value cannot be null. Parameter name: source

    Source Error:

    Line 8:          {
Line 9:              var images = Model.GetPropertyValue<List<IPublishedContent>>("image");
Line 10:             if (images.Any())
Line 11:             {
Line 12:                 <a href="@Model.Url" alt="@Model.Name"><img class="img-responsive" src="@images.FirstOrDefault().GetCropUrl(200, 200)" alt="@Model.Name"></a>

    The backend runs fine. If I outcomment the problem lines in _ProductBox.cshtml it works as well - just without images.

    The images are present in the medialibrary and the ID's matches.

    Am I missing something obvious here? Has anyone experienced this? /Jesper

    Ok -- found the answer: It seems that 

    var images = Model.GetPropertyValue<List<IPublishedContent>>("image");

    Should be:

    var images = Model.GetPropertyValue<IEnumerable<IPublishedContent>>("image");
