在extjs中追加节点时，node.updateInfo不是函数

问题描述

我正在尝试将数据加载到extjs 4 TreeStore中，但是在追加节点时，出现了node.updateInfo is not a function错误.

I am trying to load data into an extjs 4 TreeStore but while appending node, I am getting node.updateInfo is not a function error.

我的模型类如下:

Dimension.js

Ext.define('ilp.model.Dimension', {
    extend : 'Ext.data.Model',
    require : [
        'ilp.model.DimensionLevel'
    ],
    fields : [
        'actualName', 
        'displayName'
    ],
    hasMany : {model : 'ilp.model.DimensionLevel', name : 'dimensionLevels'}
});

DimensionLevel.js

Ext.define('ilp.model.DimensionLevel', {
    extend : 'Ext.data.Model',
    fields : [
        {name : 'name', type : 'string'},
        {name : 'totalTrainees', type : 'int'}
    ]
});

和树存储代码如下:

Ext.define('ilp.store.DimensionTree', {
    extend : 'Ext.data.TreeStore',
    requires : [
        'ilp.model.Dimension',
        'ilp.model.DimensionLevel'
    ],
    model : 'ilp.model.Dimension',

    root: {
    name: 'Dimensions'
    },

    proxy: {
    type: 'ajax',
    url: 'http://localhost:8080/pentaho/content/cda/doQuery',
    reader: {
            type: 'pentahoReader',
        root: 'resultset'
    },
    extraParams: {
        path: 'RINXDashboards%2FCDAs%2FILP_Employee_Qeries.cda',
        dataAccessId:'Get_All_Levels_From_All_Dimensions',
        userid : 'joe',
        password : 'password'
    }
    },

    listeners: {
    append : function(parentNode, newNode, index, options) {
            if(newNode.get('text') != 'Root') {
        console.log('newNode text value = ' + newNode.get('text'));
        newNode.set('checked', null);
        newNode.set('expandable', true);
        if(Ext.ClassManager.getName(newNode) == "ilp.model.Dimension") {
            newNode.set('expanded', true);
        newNode.set('text', newNode.get('displayName'));
        if(newNode.dimensionLevels().getCount() > 0) {
            newNode.dimensionLevels().each(function(level) {
            newNode.appendChild(level);
        });
        } else {
        newNode.set('leaf', true);
              }
        }else if(Ext.ClassManager.getName(newNode) == "ilp.model.DimensionLevel") {
            newNode.set('leaf', true);
        newNode.set('text', newNode.get('name'));
        }
    }
      }
    }
});

我在以下行上遇到了以上错误:newNode.dimensionLevels().each(function(level) {

I am getting above error on following line : newNode.dimensionLevels().each(function(level) {

在调试时，我发现newNode的updateInfo()方法是undefined.

while debugging I have found that updateInfo() method of newNode is undefined.

任何人都可以告诉我为什么会出现此错误吗?我现在已经一无所有了！！！

Can anyone please tell me why this error is coming? I am totally clueless now !!!

推荐答案

可能是由于EXTJSIV-6051错误

May this is caused by the bug EXTJSIV-6051
