Hey All,

I have defined a TreeCombo. The combo is supposed to get a string(which contains some nodes) and then mark those nodes as checked, but I cannot get a node using getNodeById().

Below is part of the TreeCombo code.

Plz help.

Here is the part code of treeComboBox.
Ext.define('xxx.TreeComboBox', {
    extend: 'Ext.form.field.ComboBox',
    url: '',
    tree: {},
    textProperty: 'text',
    valueProperty: '',
    initComponent: function () {
        Ext.apply(this, {
            editable: false,
            queryMode: 'local',
            select: Ext.emptyFn

        this.displayField = this.displayField || 'text',
        this.treeid = Ext.String.format('tree-combobox-{0}', Ext.id());
        this.tpl = Ext.String.format('<div id="{0}"></div>', this.treeid);

        if (this.url) {
            var me = this;
            Ext.create('Ext.data.TreeStore', {
            	storeId: 'treeComboStore',
            	autoLoad: true,
                sorters: [
                        property: 'leaf',
                        direction: 'ASC'
                        property: 'text',
                        direction: 'ASC'
                folderSort: true,
                proxy: { 
                	type: 'ajax', 
                	url: this.url
                fields: [
                         {name: 'text', type: 'string'},
                         {name: 'id', type: 'string'}
            this.tree = Ext.create('Ext.tree.Panel', {
                rootVisible: false,
                autoScroll: true,
                height: 200,
                store: 'treeComboStore'

            this.tree.on('itemclick', function (undefined, record) {
                me.checkChildren(record, !record.get('checked'));                	
                me.checkParent(record, record.get('checked'));
Here is the code to create the treeCombo.
	var treeCombo = Ext.create('xxx.TreeComboBox', {
		id: 'treecombo',
		fieldLabel: param,
	    renderTo: 'treeCombo',
	    width: 250,
	    url: '......json'

	var items = checkedItem.split(',');  
	var treeStore = Ext.data.StoreManager.lookup('treeComboStore');
	for(var i=0;i<items.length;i++){
		var record = treeStore.getNodeById(items[i]);
		alert("record = "+record.get('text'));
