Question

这是我的Sencha Touch 2代码，它显示Ext.data.List组件中的JSON列表数据。我用tpl来创建列出的项目。现在我需要将此列表转换为嵌套列表。但失败了，我不知道如何将列表视图的itemTpl移动到Nest List的getItemTextTpl？

带列表的代码

    Ext.define('Mobile.view.ActionListView', {
        extend: 'Ext.dataview.List',
        xtype: 'actionsummary',
        id: 'actionsummaryList',

        config: {
            title: 'Actions',

            store: 'ActionSummaryStore',
            //data:[{"Id":1,"TransactionType":"Transaction 1","ActionList":[{"Id":1,"Count":4,"Action":"Action Item 1","CurrentStatus":"Open"},{"Id":2,"Count":14,"Action":"Action Item 3","CurrentStatus":"Open"},{"Id":3,"Count":44,"Action":"Action Item 5","CurrentStatus":"Close"}]}],
            emptyText: 'Loading action items...',
            itemTpl: Ext.create('Ext.XTemplate', '<tpl for=".">',
                                                    '<div class="action-item-container"><p class="action-text">{TransactionType}</p>',
                                                          '<tpl for="ActionList"><tpl for=".">',
                                                                '<div><ul>',
                                                                   '<li><a href="javascript:void(0)"><span class="action-count">{CurrentStatus}<tt>({Count})</tt></span><span class="btn-{Action}">{Action}</span></a></li>',                                                               

                                                                 '</ul></div>',
                                                            '</tpl></tpl>',
                                                     '</div>',
                                                   '</tpl>'

                               )
        }
    });

嵌套列表的新代码

    Ext.define('Mobile.view.ActionListView', {
        extend: 'Ext.dataview.NestedList',
        xtype: 'actionsummary',
        id: 'actionsummaryList',

        config: {
            title: 'Actions',

            store: 'ActionSummaryStore',
            useTitleAsBackText: false,
            onItemDisclosure: true,

            //data:[{"Id":1,"TransactionType":"Transaction 1","ActionList":[{"Id":1,"Count":4,"Action":"Action Item 1","CurrentStatus":"Open"},{"Id":2,"Count":14,"Action":"Action Item 3","CurrentStatus":"Open"},{"Id":3,"Count":44,"Action":"Action Item 5","CurrentStatus":"Close"}]}],

            itemTpl: Ext.create('Ext.XTemplate', '<tpl for=".">',
                                                    '<div class="action-item-container"><p class="action-text">{TransactionType}</p>',
                                                          '<tpl for="ActionList"><tpl for=".">',
                                                                '<div><ul>',
                                                                   '<li><a href="javascript:void(0)"><span class="action-count">{CurrentStatus}<tt>({Count})</tt></span><span class="btn-{Action}">{Action}</span></a></li>',

                                                                 '</ul></div>',
                                                            '</tpl></tpl>',
                                                     '</div>',
                                                   '</tpl>'

                               )
        },

        getTitleTextTpl: function () {
            return 'Summary View';
        },
        getItemTextTpl: function (node) {
           // return '<div><strong>{name}:</strong> <em>{description}</em></div>';
           //replace this code with my above itemTPL
        }
    });

使用这种模型，我不会使用NestedList，但是这样的

Ext.Loader.setConfig({
    enabled: true

Ext.application({

    launch: function() {

        var navigationview = Ext.create('Ext.navigation.View', {

        navigationview.push(branchlist);
