[CLOSED] Error on Form Submit - parsedResponse.result

[OriCoder]

I am having a similar problem on a couple of forms that #i have in my web app, firebug returns:

TypeError: parsedResponse.result is undefined

...cope.parseResponse(response,options);if(!Ext.isEmpty(parsedResponse.result.docum...

    
ext.axd?v=33683 (line 128, col 62)

A sample form view is

@(Html.X().Window()
    .Width(478)
    .Height(600)
    .Icon(Icon.ApplicationFormAdd)
    .Title("Trade Loss - Additional Notes")
    .ID("TradeLossAdditionalNotesWindow")
    .Padding(10)
    .X(400)
    .Y(150)
    .CloseAction(CloseAction.Destroy)       // NEED TO MAKE THIS THE SAVE FUNCTION??
    .Items(
   Html.X().FormPanel()
    .Layout(LayoutType.VBox)
         .ID("TradeLossForm")
    .LayoutConfig(new VBoxLayoutConfig { Align = VBoxAlign.StretchMax })
    .Items(
        Html.X().Label()
        .Text("Please give further information of recorded loss.")
        .Margin(5)
        ,
        Html.X().FieldContainer()
            .Width(450)
            .MarginSpec("5 5 5 0")
            .Padding(5)
        .Items(
            Html.X().Label().Text("Additional Notes:").Width(370).Padding(5),
            Html.X().TextArea().ID("AdditionalNote").Width(445).Padding(5)                   
            )
            ,
        // submit button
            Html.X().FieldContainer()
            .Width(300)
            .MarginSpec("5 5 5 0")
            .Padding(5)
            .Items(
                Html.X().Button()
                .Text("Submit")
                .DirectEvents(de =>
                    {
                        de.Click.Url = Url.Action("setTradeLossAdditionalNote");
                        de.Click.ExtraParams.Add(new Parameter("AdditionalNote", "App.AdditionalNote.getValue()", ParameterMode.Raw));
                        // extra params int RIABargainRef, string AdditionalNote
                        de.Click.Success = "App.TradeLossAdditionalNotesWindow.Close();";
                    }
                )

            )
        )
    )
)

the controller code is

        public ActionResult setTradeLossAdditionalNote( string AdditionalNote) {

            TradeLossReason TradeLossReason;

            try
            {
                TradeLossReason = (from ofg in db.TradeLossReason                                  
                                   select ofg).First<TradeLossReason>();

                TradeLossReason.AdditionalNote = AdditionalNote;

                // save changes to DB
                db.SaveChanges();
            }

            catch (InvalidOperationException e)
            {

                TradeLossReason = new TradeLossReason();
                TradeLossReason.Reason = 4;                         // set this to additional note
                TradeLossReason.AdditionalNote = AdditionalNote;

                // add to DB and save changes
                db.TradeLossReason.Add(TradeLossReason);
                db.SaveChanges();

            }

            // Notify user of change
            X.Msg.Notify("Trade Loss Reason", "Additional Notes saved").Show();

            return this.Direct();
        }

Also, as an aside, what is the best way of closing the window once the details have been submitted?

Thanks
