Tree: Add node sorted

[dherbolt]

Hi all,
Is there any way how to add node into tree with applied sort? I have defined Ext.data.TreeStore with sorter, but it is applied only when data are loaded.
If I add node into tree by parentNode.appendChild(node), the node is added as last child of parent (I know, it's append). But how I can add node according to current sort state?
I'm looking for something like Ext.data.Store.addSorted.

Thanx for advice.

In ExtJS 3, TreeNode.appendChild adds new node to proper position according to current sort state if Ext.tree.TreeSorter is defined for the Tree.

If all else fails, you always manually call the sort method of Ext.data.TreeStore, after adding your new node.

Yes, I know. But I don't want to sort whole store I added only one node. It is enough to sort only items of parent node.

Yes, it works, but only when I use:

Ext.getCmp('treepanel-1009').getRootNode().appendChild({text: '0a'});
Ext.getCmp('treepanel-1009').getStore().sort(this.generateComparator());

It is "user unfrendly" because I have to call sort manually after append.

If I use store's "append" event:

var store = Ext.getCmp('treepanel-1009').getStore();
store.on('append', function () {this.sort(this.generateComparator())}, store);

I get TypeError exception:

TypeError: sibling is undefined

Tested on xml tree example from ExtJS 4.1.1 package.
