Bug in Page_AjaxLoadComplete(object sender, EventArgs e)

[jeybonnet]

Hi guys,

I think I have found a bug in Coolite ScriptManager.


Sometimes, on a AjaxEvent, I have a nullReferenceException in Page_AjaxLoadComplete(object sender, EventArgs e).


By placing Log lines into your source code, I found the line where program fails.

    XmlNode eventArgumentNode = this.SubmitConfig.SelectSingleNode("config/__EVENTARGUMENT");

I think the nullReference is caused by SubmitConfig to null.
In my aspx page, I have

<%@ Page Title="" Language="C#" AutoEventWireup="true" CodeBehind="Manage.aspx.cs"
    Inherits="Example.Web.Manage" EnableViewState="false" %>

<ext:ScriptManager runat="server" ID="ScriptManager1" StateProvider="None">
    </ext:ScriptManager>

I figure this error occurs when

if (Ext.IsAjaxRequest && !this.Page.IsPostBack)

IsAjaxRequest is to True and this.Page.IsPostBack = false
First, I don't understand when this case can occur !!
I will continue to investigating.
Thks

More information,

It occurs when

   if (Ext.IsAjaxRequest && !this.Page.IsPostBack)

I can't understand when this happens.
