打开extjs时，折叠面板不会创建滚动

Question

EXT V. 3.01

我有一个带边框布局的视口。

中心区域是一个tabpanel。

tabpanel活动选项卡在vbox布局中保存2个面板。

1）搜索小组。

2）网格转换面板。

搜索面板有2个字段集：

1）基本搜索

2）高级搜索

默认情况下，高级搜索字段集已折叠。

问题是，当我展开高级搜索字段集时，它会向下推动结果网格，但是没有滚动被打开，因此网格被推出视图而没有任何方法来丰富它。

我想在高级搜索字段集扩展时添加滚动。

以下是一些可能有用的代码：

Ext.extend(Ext.Viewport, {
     constructor: function (config) {
        config = Ext.apply({
        layout: 'border',
        items:[
            new Ext.TabPanel({
                activeTab: 0,
                region: 'center',
                items:[{
                        xtype:'panel',
                        title: this.localize.FillDetails,
                        layout: 'vbox',
                        items:[
                            this.searchPanels,
                            this.chooseInvoiceGrid
                        ]
                    }
                ]
            })
        ]
    },config);
     }
}

这是我的网格配置：

config = Ext.apply({
        store: this.storeProvider.getArChooseInvoiceStore(),
        stripeRows:true,
        loadMask: true,
        autoExpandMax: 2000,

            emptyText: this.localize.NoInvoiceToDisplay

        listeners: {
            // prevents default browser menu on client right click.
            render: function (grid) {
                grid.getEl().on('contextmenu', Ext.emptyFn, null, { preventDefault: true });
            },
            rowdblclick : this.onInvoiceClick 
        },
