ItemSelector rendering problem in 4.1 Beta

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?

Code:

---

    /*
    * Ext.ux.form.ItemSelector Example Code
    */
    var isForm = Ext.widget('form', {
        title: 'ItemSelector Test',
        width: 700,
        bodyPadding: 10,
        height: 300,
        renderTo: 'itemselector',
        layout: 'fit',
        items:[{
            xtype: 'itemselector',
            name: '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'
        }],
        dockedItems: createDockedItems('itemselector-field')
    });

If you run it off of the file system then yes it won't work but running it off of a web server works just fine.

I ran it from a web server and it is still blank.

I just downloaded 4.1 Beta2, it shows up now.

can not run it inside Ext.window.Window().

I have the same issue, just a blank area.

I had a similar problem in 4.0.7 but i was able to get around it by creating the widget during the load event of the store.

Make sure the Itemselector Element hast it's own height and width property. That should do it for the beta.
