そのため、別のディレクトリにあるストアのデータを含むグリッドを表示する次のコードがあります。

Ext.require([
    'Ext.ux.form.ItemSelector', 
    'Ext.grid.plugin.RowExpander', 
    'Ext.grid.*', 
    'Ext.data.*',  
    'Ext.selection.CheckboxModel',
    'Ext.toolbar.Paging',
]);

Ext.define('AM.view.metadata.List' ,{
    extend: 'Ext.grid.Panel',
    alias: 'widget.metadatalist',
    title: '<center>Results</center>',
    store: 'Metadata', 
    requires: ['Ext.ux.RowExpander'],   
    initComponent: function() {
        this.columns = [
            {header: 'Technical Name',  dataIndex: 'TECH_NAME', //...
            //...
        ];
        this.callParent(arguments); //Calls the parent method of the current method in order to override 

    },
    dockedItems: [
        {
        xtype: 'toolbar',
        dock: 'bottom',
        items: [
            { xtype: 'tbtext',  text: 'Loading...', id: 'recordNumberItem'  },
            '-',
            { text: 'Expand All', id: 'expand' },
            '-',
            { text: 'Collapse All', id: 'collapse' },
            '->',
                    //Paging ToolBar
            { xtype: 'pagingtoolbar', dock: 'bottom', store: 'Metadata', pageSize: 3, displayInfo: true, emptyMsg: 'No items to display',  displayMsg: 'Displaying topics {0} - {1} of {2}' },

            '->',
            { text: 'Print', itemId: 'print' },
            '-',
            { text: 'Export', itemId: 'export' }
        ]
    }],
    plugins: [{
            ptype: 'rowexpander',
            rowBodyTpl : [
                //...
                            //...
            ]
        }]

ページング ツールバーには問題はありませんが、データがロードされていることや、スクロールできることさえ表示されません。私の店には現在14列あります。（ストアは問題なくロードされます）。私はプロキシを使用していません。

ここが私の店です。Metadata.js
