If you have .NET 3.5 installed (i.e. any beta version of VS2008), you =
will
need a fix to Anthem.Manager that I posted in CVS.

Subject: [Anthem.NET-users] Difficulty in getting started (1.5.1)

Hi all,
I'm trying to get my local machine working with just a simple Anthem
project, but running into problems with the latest release 1.5.1.
Essentially I've built the 2005 project perfectly fine (in release mode) =
and
then referenced the built Anthem.dll from my test project. This consists =
of
just two files (at bottom of mail).

I've tried with and without Anthem.Manager.Register(this); in my =
Page_Load
handler to no avail, everytime I click the linkbutton and trigger the
callback I get an exception:

	ApplicationException: This page was never registered with
Anthem.Manager!
	Anthem.DLL!Anthem.Manager.GetManager() Line 251
=09
Anthem.DLL!Anthem.Manager.WriteValueAndError(System.Text.StringBuilder =
sb =3D
{{"value":null,"error":"This page was never registered with
Anthem.Manager!"}, object val =3D null, string error =3D "This page was =
never
registered with Anthem.Manager!", string viewState =3D null, string
viewStateEncrypted =3D null, string eventValidation =3D null,
System.Collections.Hashtable controls =3D null, string[] scripts =3D =
null) Line
1125 + 0x5 bytes
	Anthem.DLL!Anthem.Manager.WriteResult(System.IO.Stream stream =3D
{System.Web.HttpResponseStreamFilterSink}, System.IO.MemoryStream =
htmlBuffer
=3D {System.IO.MemoryStream}) Line 2168 + 0x28 bytes
	Anthem.DLL!Anthem.CallBackFilter.Close() Line 2232 + 0x15 bytes

Digging into this shows that something screwy seems to be happening =
here:

	private static string GetAnthemManagerKey()
        {
            Page page =3D HttpContext.Current.Handler as Page;
            if (page =3D=3D null)
            {
                return "Anthem.Manager.Handler";
            }
            else
            {
                return "Anthem.Manager." + page.ToString();
            }
        }

With "page" evaluating to null and so returning the incorrect key?

Anyone had a similar problem? I'm tearing my hair out because the =
framework
looks fantastic - a really lightweight alternative to Atlas!
