I am very new to extjs and going through the documentation. http://docs.sencha.com/ext-js/4-0/#!...and_containers. In the section 'container', there is the following code which is not doing anything on my page(blank page, no panels)


Ext.create('Ext.panel.Panel',{ renderTo:Ext.getBody(), width:400, height:300, title:'Container Panel', items:[{ xtype:'panel', title:'Child Panel 1', height:100, width:'75%'},{ xtype:'panel', title:'Child Panel 2', height:100, width:'75%'}]});
Please check this and help me..

Thanks.
