RowExpander doesn't shown -> namespace is undefined

[wqjh7809]

Hello, I've got an error by using the RowExpander (ExtJS 4.1.1). With the following code I get an error:

 /**
         * Supports namespace rewriting
         * @private
         */
        parseNamespace: function(namespace) {

....

because the namespace is undefined. Is there an error in my code? Without the rowexpander I get no error and the grid works.

Ext.application({
    name: 'test',
    launch: function () {
        Ext.define('myModel', {
            extend: 'Ext.data.Model',
            fields: [
                { name: 'name1', type: 'string' },
                { name: 'name2', type: 'string' }
            ]
        });
        var myStore = Ext.create('Ext.data.Store', {
            model: 'myModel',
            data: [
                {
                    name1: 'Test Name 1',
                    name2: 'Test Name 2'
                }               
            ]
        });  
        var myGrid = Ext.create('Ext.grid.GridPanel', {
            title: 'Test Grid',
            id: 'grid',
            store: myStore,
            columns: [
                { header: 'Name', dataIndex: 'name1' }
            ],
            plugins: [{
                ptype: 'rowexpander',
                rowBodyTpl: new Ext.XTemplate(
                    '<p><b>Title:</b> {name1}</p>',
                    '<p>{name2}</p>'
                )
            }],
            renderTo: Ext.getBody()
        });
    }
});
