_pristine is undefined in an empty DataSource with schema.total specified

[Dirk]

This code:

var MyModel = kendo.data.Model.extend();
var MyDataSource = kendo.data.DataSource.extend({
    options: {
        transport: {
            create: {
                url: 'dummy.json',
                type: 'GET',
                dataType: 'json'
            },
            read: {
                url: 'dummy.json',
                type: 'GET',
                dataType: 'json'
            },
            update: {
                url: 'dummy.json',
                type: 'GET',
                dataType: 'json'
            },
            destroy: {
                url: 'dummy.json',
                type: 'GET',
                dataType: 'json'
            }
        },
        schema: {
            model: MyModel,
            data: 'data',
            total: 'total'
        }
    }
});

var myDataSource = new MyDataSource();
var myModel = new MyModel({
    ding: 'dong',
    ping: 'pong'
});

myDataSource.add(myModel);
myDataSource.sync();


Creates this error message:

1. Uncaught TypeError: Cannot call method 'push' of undefined kendo.web.js:6109

If schema.total is not defined everything works fine.
Unfortunately we need the total because we use a pageable Grid.

Any help or thoughts on that issue?
