[Mono-dev] 2.0 LoadControlState error in ListControl using CheckBoxList

Hi All,

In continued testing of mojoportal using the 2.0 runtime, I've run into another problem on post back when using a CheckBoxList

System.Exception: Unhandled Exception while processing NeatUpload child request ---> System.ArgumentOutOfRangeException: Index is less than 0 or more than or equal to the list count.
Parameter name: index
in <0x00096> System.Collections.ArrayList:get_Item (Int32 index)
in <0x00012> System.Web.UI.WebControls.ListItemCollection:get_Item (Int32 index)
in <0x0010f> System.Web.UI.WebControls.ListControl:LoadControlState (System.Object savedState)
in <0x00141> System.Web.UI.Page:LoadPageControlState (System.Object data)
in <0x0004d> System.Web.UI.Page:LoadPageViewState ()
in <0x0012f> System.Web.UI.Page:InternalProcessRequest ()
in <0x000aa> System.Web.UI.Page:ProcessRequest (System.Web.HttpContext context)--- End of inner exception stack trace ---

in <0x004a3> Brettle.Web.NeatUpload.UploadHttpModule:Application_BeginRequest (System.Object sender, System.EventArgs e)
in (wrapper delegate-invoke) System.MulticastDelegate:invoke_void_object_EventArgs (object,System.EventArgs)
in <0x0046f> System.Web.HttpApplication+<RunHooks>__0:MoveNext ()

I think this corresponds to this section of ListControl.cs:

#if NET_2_0
        protected internal override void LoadControlState (object savedState)
            object first = null;
            ArrayList indices = null;
            Pair pair = savedState as Pair;

            if (pair != null) {
                first = pair.First;
                indices = pair.Second as ArrayList;

            base.LoadControlState (first);

            if (indices != null) {
                foreach (int index in indices)
                    Items [index].Selected = true;

But I'm not sure what could be wrong.

Any ideas?
