The ItemSelector example that came with the 4.1 Beta downlowd shows a blank widget when I deployed. Code is in /examples/multiselect/multiselect-demo.html, multiselect-demo.js. I see a blank panel for the ItemSelector. Can someone confirm if this is indeed a problem?
     * Ext.ux.form.ItemSelector Example Code
    var isForm = Ext.widget('form', {
        title: 'ItemSelector Test',
        width: 700,
        bodyPadding: 10,
        height: 300,
        renderTo: 'itemselector',
        layout: 'fit',
            xtype: 'itemselector',

            id: 'itemselector-field',
            anchor: '100%',
            fieldLabel: 'ItemSelector',
            imagePath: '../ux/images/',
            store: ds,
            displayField: 'text',
            valueField: 'value',
            value: ['3', '4', '6'],
            allowBlank: false,
            msgTarget: 'side'
