When using MobileControls in .Net 2.0 it seems whenever a user's session times out and they do a post back they get the error:
The page requires session state that is no longer
available. Either the session has expired, the client did not send a
valid session cookie, or the session state history size is too small.
Try increasing the history size or session expiry limit.
If I disable viewstate for the page this error won't happen but I get other errors when asp.net tries to re-bind the values of drop downs.
To reproduce this issue create Default.aspx with
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<%@ Register TagPrefix="mobile" Namespace="System.Web.UI.MobileControls" Assembly="System.Web.Mobile" %>
<html xmlns="http://www.w3.org/1999/xhtml">
<body>
<mobile:Form ID="MainForm" Runat="server">
<mobile:SelectionList ID="EndPoint" SelectType="DropDown" Runat="server" BreakAfter="true">
<Item Text="Test1" Value="test1" />
<Item Text="Test2" Value="test2" />
mobile:SelectionList>
<mobile:Command ID="TestPost" Runat="server" OnClick="TestPost_Click" BreakAfter="True">TestPostmobile:Command>
mobile:Form>
body>
html>
Default.aspx.cs with:
using System;

using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.Mobile;
using System.Web.SessionState;

public partial class _Default : System.Web.UI.MobileControls.MobilePage
{

and web.config with:
<configuration>

<filter name="supportsJavaScript" compare="Javascript" argument="true" />

Then browse to Default.aspx, click the button, clear your cookies and session variables and click the button again and you'll get the error. Any help would be appreciated.
