View Full Version : Tree Scroll Error

2 Nov 2009, 8:27 AM
Hi All, I have a tree that works just fine - until you try to use the auto scrollbar (error occurs as soon as you roll over the vert. scrollbar). I get theis error in firebug:

"Permission denied to...a non-chrome context"

My tree:

var treeLoader = new Ext.tree.TreeLoader({
baseParams: {
method: 'getProjectTree'

var rootNode = new Ext.tree.AsyncTreeNode({
text: 'root',
iconCls: 'icon-grid'

var projectTree = new Ext.tree.TreePanel({
title: 'Project Navigation',
loader: treeLoader,
root: rootNode,
iconCls: 'nav',
rootVisible: false,
autoScroll: true,
useArrows: true,
height: 400

...and it's in an accordian within a viewport:

//main viewport wrapper
var viewport = new Ext.Viewport({
layout: 'border',
//items in viweport
items: [ //the header area
new Ext.BoxComponent({
region: 'north',
height: 40,
autoEl: {
tag: 'div',
html: '<div class="headerTitle">xxx Engineering Budget System</div>'
}),//the left navigation area
region: 'west',
id: 'west-panel',
title: 'Menu',
split: true,
width: 200,
minSize: 175,
maxSize: 400,
collapsible: true,
margins: '0 0 0 5',
layout: {
type: 'accordion',
animate: true
items: [
title: 'Settings',
html: '<p>Some settings in here.</p>',
border: false,
iconCls: 'settings'
new Ext.TabPanel({
region: 'center',
deferredRender: false,
activeTab: 0,
items: [
contentEl: 'center2',
title: 'Help',
closable: true,
autoScroll: true

FYI: I found some additional error messages in the firebug console:

"Resuming debugger: error during debugging loop: [Exception... "Illegal operation on WrappedNative prototype object" nsresult: "0x8057000c (NS_ERROR_XPC_BAD_OP_ON_WN_PROTO)" location: "JS frame :: XPCSafeJSObjectWrapper.cpp :: anonymous :: line 450" data: no]"

This error also seems to only happen in FireFox.
