    Default TreeStore getNodeById fails to get the node

    TreeStore getNodeById fails to get the node


    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.
    Code:
    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'));
                	me.setValue(me.getSelectedValue(me.tree.getRootNode()));
                });
    Here is the code to create the treeCombo.
    Code:
    	var treeCombo = Ext.create('xxx.TreeComboBox', {
    		id: 'treecombo',
    		fieldLabel: param,
    	    renderTo: 'treeCombo',
    	    width: 250,
    	    url: '......json'
    	});
    	
    
    
    	treeCombo.setValue(checkedItem);
    	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'));
    		treeCombo.fireEvent('itemclick',this,record);
            }

    I have solve the pro somehow. If I use storeId for store instead of some variable, the getNodeById works fine in IE, but it still won't work in Chrome.

    Could you help me with this?
