Uncaught TypeError on date field when jsonp returns null value

[andy370]

My model:

Ext.define('MyApp.model.InvoiceLookup_Model', {
    extend: 'Ext.data.Model',
    config: {
        fields: [{
                name: 'invoiceId'
            },{
                name: 'transactionDate',
                type: 'date'
            },{
                name: 'invoiceNumber'
            },{
                name: 'invoiceTotal'
            },{
                name: 'invoiceStatus'
            }
]}});

gets populated via jsonp:

{"invoiceId":null,"invoiceTotal":null,"invoiceNumber":null,"invoiceStatus":null,"transactionDate":null}

gives me this error:

Uncaught TypeError: Cannot call method 'toString' of null sencha-touch-all-debug.js:18098

But the error (and formatting on non-null records) goes away if I take away the type: 'date' property. Is this a bug or am I doing something wrong?

With this store:

new Ext.data.Store({
    autoLoad  : true,
    model     : 'MyApp.model.InvoiceLookup_Model',
    proxy     : {
        type : 'jsonp',
        url  : 'data/php.php'
    },
    listeners : {
        load : function() {
            console.log(arguments);
        }
    }
});

and exactly this response (actual JSONP not JSON)

Ext.data.JsonP.callback1({"invoiceId" : null, "invoiceTotal" : null, "invoiceNumber" : null, "invoiceStatus" : null, "transactionDate" : null});

I do not get any errors in 2.0.1.1, 2.1.0 RC1

Sorry, I didn't show you my actual response:

Ext.data.JsonP.callback11({"invoiceId":null,"invoiceTotal":null,"invoiceNumber":null,"invoiceStatus":null,"transactionDate":null});

On a hunch I changed:

<script src="../sencha-touch-2.1.0-b1/sencha-touch-all-debug.js"></script>

To:

<script src="../sencha-touch-2.1.0-b1/sencha-touch-all.js"></script>

In my index.html and *tada*, it's working. So apparently debug has a bug in it.
