Javascript error when using Messenger Connect client-side library in ASP.NET

2.1k Views Asked by Klemen Slavič At 11 April 2025 at 04:05

I'm having a problem implementing the new Messenger Connect functionality inside an existing Sitefinity site to enable client logins using Live IDs.

Namely, when I'm using the following code to implement the client-side functionality:

<head runat="server">
  <script type="text/javascript" src="http://js.live.net/4.1/loader.js"></script>
</head>
<body>
  <form runat="server" id="form1">
    <asp:ScriptManager ID="ScriptManager1" runat="server"/>
    <wl:app
        client-id="<%= ConfigurationManager.AppSettings["wl_wrap_client_id"] %>"
        scope="WL_Profiles.View"
        callback-url="<%= ConfigurationManager.AppSettings["wl_wrap_client_callback"] %>?wl_session_id=<%=SessionId %>"
        channel-url="/channel.htm">
    </wl:app>

... I get three errors in Firebug that I can't quite identify correctly:

Sys.ArgumentTypeException: Object of type 'Sys._Application' cannot be converted to type 'Sys.IDisposable'. Parameter name: object

(in ScriptResource.axd?d=.... line 4993)

Sys.Application._doInitialize is not a function

(in MicrosoftAjaxBase.js line 1)

Sys.InvalidOperationException: The script 'MicrosoftAjaxGlobalization.js' has been referenced multiple times. If referencing Microsoft AJAX scripts explicitly, set the MicrosoftAjaxMode property of the ScriptManager to Explicit.

(in ScriptResource.axd?d=.... line 984)

The errors are only triggered when I include the loader.js script from js.live.net.

EDIT: Seems the errors aren't necessarily triggered in that order. Refreshing the page seems to shuffle those errors and/or introduce other ones, such as a Sys.ParameterCountException in ScriptResource.axd?... on line 1842, for example.

Hey, I tried some combinations here, and the one that worked was:

1) Set the ScriptMode property of the ScriptManager to Release;

2) Load the MSN library in the CodeBehind Page_Load event, using the ClientScript class:

protected void Page_Load(object sender, EventArgs e)
{
    ClientScript.RegisterClientScriptInclude(this.GetType(), "live", "http://js.live.net/4.0/loader.js");
}

Firebug isn't showing any error anymore, and in my case, the authentication window is opening as desired.

Hope it helps!

EDIT

As told before, here follows the whole code I use to avoid this issue:

To see it running, you can access http://labs.asteria.com.br/wlm. It seems that the Consent URL (https://consent.live.com/AccessToken.aspx) is not responding at this time.
