View Full Version : panel collapse containing 'object' in IE

16 May 2011, 12:25 AM
below is a simplified sample to explain the issue.
Viewport west region containing a panel whose 'contentEl' contains an '<object>' tag( eg. a youtube video embedding).

On collaspse/expand the region in Internet explorer is flickering the whole UI. Looks like everything is refreshed and rendered again in the page.

The behaviour is proper in chrome.

Ext.onReady(function () {

var west = new Ext.Panel({
region: 'west',
margins: '5 0 5 5',
split: true,
width: 350,
collapsible: true,
contentEl: 'westContent'

var viewport = new Ext.Viewport({
layout: 'border',
items: [
west, {
region: 'center',
margins: '5 5 5 0',
cls: 'empty',
bodyStyle: 'background:#f1f1f1',
html: '<br/><br/>&lt;empty center panel&gt;'

<div id='westContent'>
<object type="application/x-shockwave-flash" width="425" height="350" data="http://www.youtube.com/v/HvfNl-kkqYs"><param name="movie" value="http://www.youtube.com/v/HvfNl-kkqYs" /></object>
