Hi,

My Error is:

Microsoft JScript runtime error: Unable to get value of the property '_staticInstance': object is null or undefined.

My asmx service code:

[WebMethod]
       public string RedirectToLogin(string UserControl, string language, string country, string steps)
       {
           string redirectpage = string.Empty;
           Langauge.RequestRedirectPage Rp = new Langauge.RequestRedirectPage();
           redirectpage = Rp.getRedirectPage(UserControl, language, country, steps);
           return redirectpage.ToString();
       }

My Javascript code:

function load123() {
        Namespace1.RedirectToLogin("Registration", "dk", "denmark", "step2", onSuccess123, onfailedfun);
    }


function onSuccess123(resul) {
    window.location = resul;
    }
    function onfailedfun(res) {
    }

service calling from aspx page:

<asp:ScriptManager ID="ScriptManager2" runat="server">
           <Services>
               <asp:ServiceReference Path="~/Shop.asmx" />
           </Services>
       </asp:ScriptManager>

Runtime getting from JSDebug[dynamic] page:

Shop._staticInstance.RedirectToLogin(UserControl,language,country,steps,onSuccess,onFailed,userContext); }

thanks in advance.
