[2.0][DUP][SOLVED] Cannot close tab panel with un-rendered buttons

[markporter]

Using ext-base
windows,linux,firefox 2, ie 6

When closing a tab that contains un-rendered buttons array, an error is thrown. In this example, closing the tab, without activating it first, generates an error. Adding the deferredRender:false option to the tabPanel config fixes the problem, but it defeats the purpose of config objects if their contents must be rendered even if not displayed.

This is not a problem in [2.0beta1]

Ext.onReady(function(){
        new Ext.Viewport({
            items:[{
                xtype:"tabpanel",
                id:"tabs",
                items:[{
                    title:'button',
                    closable:true,
                    buttons:[{text:"dude"}]
                }]
            }]
        });
    }); 

errors:
