Hi all

I have added a new property to the Image media type called Link which is a Content Picker. It is optional.

I'm using the contents of a media folder to populate an image slider, and therefore need the link property for the hyperlink of each slider (or not if the user decides they dont want a link for that particular image.)

I'm using a simple partial (snippet below), but it's throwing an error if an image has no link property set.

This is version 7.0.2. How do I handle null properties?

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage
<ul class="example-orbit" data-orbit>

    @foreach (var item in @Umbraco.Media(1148).Children)
    {
    <li>
        @{
            var link = "#";
        }
        @if (null != @item.link)  // get error here
        {
            link = @Umbraco.Content(item.link).Url;
        }
        <a data-reveal-id="myModal" href="@link">
            <img src="@item.Url" alt="@item.Name" />
        </a>
    </li>

    }
</ul>

Exception:

An exception of type 'System.ArgumentNullException' occurred in Umbraco.Core.dll but was not handled in user code

Additional information: Value cannot be null
