Unable to render panel in Chrome. Works well in Firefox

Hello,

I am trying to render a panel. It works well in Firefox but gives the following error when I try it in Chrome:

Uncaught TypeError: Cannot call method 'applyStyles' of null

The code that I have used is:

var userDlg = new myDialog();
        
    var contentPanel = {
        id: 'content-panel',
        region: 'center',
        layout: 'card',
        margins: '2 5 5 0',
        activeItem: 0,
        border: false,
        items: userDlg
    };


    var viewport = new Ext.Viewport({
        layout: 'border',
        title: 'Ext Layout Browser',
        items: [contentPanel],
        renderTo: Ext.getBody()
    });

Can anyone point out the error?

Thanks in advance.

Just tried this and it works:

    var contentPanel = {
        html : 'hi',
        region: 'center',
        layout: 'card',
        margins: '2 5 5 0',
        activeItem: 0,
        border: false
    };


    var viewport = new Ext.Viewport({
        layout: 'border',
        items: [contentPanel]
    });

This is your code with some changes. I removed renderTo and title from the Ext.Viewport as they are not supported. I removed the items config in the contentPanel Object as I didn't have that dialog class and to make sure it's rendering added the html config. This rendered fine in Chrome 16.

Sorry!
