Im defining a vieport like this:

items: [{
region: 'north',
height: 80,
border: false,
collapsible: false,
contentEl: 'northBound'
}, {
region: 'south',
height: 28,
border: false,
buttonAlign: 'left',
collapsible: false,
xtype: 'southpanel'

}, {
region: 'west',
id: 'west',
border: false,
title: "Navigator",
width: 250,
minSize: 175,
maxSize: 400,
collapsible: true,
layoutConfig: {
animate: false
layout: 'accordion'
}, {
region: 'center',
id: 'center',
border: false,
layout: 'fit',
items: [],
defaults: {
autoScroll: false

and than im trying to change the components of the viewport with this:


but im getting this in the console:

TypeError: this.config[a].destroy is not a function

When i try it again than it works but before it was working fine in 3.0.0. What i am doing wrong here or is it a bug ?

So, after experiencing so many bugs in ExtJs 3.4 i finalized all this history of problems by setting the content to IE8 for a compability issue in IE9 !

So for other people out there looking for a solution for this (might be old but gold):
