Using nestedlist as an xtype throws the error Uncaught TypeError: Cannot call method 'getRootNode' of undefined

No matter what else is defined in it, xtype: 'nestedlist' will throw the error.


I was trying to implement this kitchensink nestedlist example as an xtype:


var nestedList = new Ext.NestedList({
fullscreen: true,
items: [{
text: 'Option A',
items: [{
text: 'Option A.1',
customAttribute: 123,
items: [{
text: 'Option A.1.a'
},{
text: 'Option A.1.b'
}]
},{
text: 'Option A.2',
customAttribute: 389
}]
},{
text: 'Option B',
items: [{
text: 'Option B.1',
customAttribute: 233
},{
text: 'Option B.2',
customAttribute: 2390
}]
},{
text: 'Option C',
items: [{
text: 'Option C.1',
customAttribute: 903
},{
text: 'Option C.2',
customAttribute: 77
}]
}]
});
