We're using EPiServer 6 R2, PTB and Find

My guess is that the problem is that we're using a EPiServer.Web.Hosting.VirtualPathNativeProvider for one of our VPPs.

I've registered the bug. You can however overload the default Url-projection for UnifiedFiles in UnifiedSearch by:

                .ProjectUrlFrom(x => x.GetUrl());

public static string GetUrl(this UnifiedFile file)
        return null;

    if (Global.UrlRewriteProvider != null)
        var url = new UrlBuilder(file.PermanentLinkVirtualPath);
        Global.UrlRewriteProvider.ConvertToExternal(url, null, UTF8Encoding.UTF8);
        return url.ToString();
    return file.PermanentLinkVirtualPath;

Thanks Henrik,

I will try it out. We are not able to select Find as a product here when registering a new incident.

Thanks for notifying us. I've requested that Find should be added.

Hi again,

That didn't actually solve the bug. Now all url's are null for files. But I'm just searching in my local EPiServer database, so I can rely on the url-rewriter when renderingen the url's.

Now I'm just returning the VirtualPath and that works great.

    .ProjectUrlFrom<UnifiedFile>(file => file.VirtualPath));
