MVC SiteMap Hiding a node from menuhelper, but display in sitepathhelper (breadcrumbs)

Question

I'm trying to hide a node from my site menu, but display it in my breadcrumbs

I'm following the tutorial here: https://github.com/maartenba/MvcSiteMapProvider/wiki/Advanced-Node-Visibility

<mvcSiteMapNode title="Create Customer" controller="Customer" action="Create" area="Home" clickable="false" visibility="SiteMapPathHelper,!*"/>  

The above doesn't seem to work. It shows up both in my site menu, and breadcrumbs.

We created an OnlyBreadCrumbMVCSiteMapNodeAttribute. We decorate any code we want the attribute

public class OnlyBreadCrumbMvcSiteMapNodeAttribute : MvcSiteMapNodeAttribute
{
    public OnlyBreadCrumbMvcSiteMapNodeAttribute(string title, string parentKey)
    {
        Title = title;
        ParentKey = parentKey;
        VisibilityProvider = typeof(BreadCrumbOnlyVisibilityProvider).AssemblyQualifiedName;
    }
    public OnlyBreadCrumbMvcSiteMapNodeAttribute(string title, string parentKey, string key)
    {
        Title = title;
        Key = key;
        ParentKey = parentKey;
        VisibilityProvider = typeof(BreadCrumbOnlyVisibilityProvider).AssemblyQualifiedName;
    }
}

Also have a visibilty provider

public class BreadCrumbOnlyVisibilityProvider : ISiteMapNodeVisibilityProvider
{
    public bool IsVisible(SiteMapNode node, HttpContext context, IDictionary<string, object> sourceMetadata)
    {
        if (sourceMetadata["HtmlHelper"] == null || (string)sourceMetadata["HtmlHelper"] == "MvcSiteMapProvider.Web.Html.SiteMapPathHelper")
        {
            return true;
        }
        return false;
    }
}

Use like

    [OnlyBreadCrumbMvcSiteMapNode("Upload Documents", "AssetDocuments")]
    public virtual ActionResult FileUpload(int assetId)

Upload Documents will be breadcrumb title. AssetDocuments is the Parent Key

If you pass the 3rd parameter, that sets a key of the breadcrumb node itself
