    MultiNodeTreePicker check deleted nodes

    I use the MultiNodeTreePicker for picking related content.

    When a node is deleted with is in use by te MultiNodeTreePicker my razor code gets an error.

    Is is possible to check if a node exists?

    @if(@CurrentPage.HasValue("related"))

{
    <ul> 
        @foreach (var item in @CurrentPage.related.ToString().Split(','))
        {
        var page = Umbraco.TypedContent(item);



            <li>
                <a href="@page.Url">
                    @page.Name
                </a>
            </li>   


        }
    </ul>
}

    Hello Bas

    this should work :) 

    @if(@CurrentPage.HasValue("related"))
{
<ul> 
    @foreach (var item in @CurrentPage.related.ToString().Split(','))
    {
    var page = Umbraco.TypedContent(item);


          if(page != null){
          <li>
            <a href="@page.Url">
                 @page.Name
            </a>
        </li>   
    }
    }
</ul>

    }
