javascript - Extjs 5.1 : overflowHandler: 'Menu' not working correctly for toolbar

Question

我正在使用属性 overflowHandler: 'Menu' 来配置我的工具栏

但是当我单击按钮以显示其余按钮时，它显示了一个空列表

Ext.create('Ext.toolbar.Toolbar', {
        layout: {
         overflowHandler: 'Menu'
         },
        items: [
            {
                iconCls: 'add',
                text: 'Add external document',
                handler: 'onAddClick'
                //menu: Ext.create('bdociTabletProto.view.folder.list.DocumentsList')
            },
            {
                iconCls: 'delete'
            },
            {
                iconCls: 'edit'
            },
            {
                iconCls: 'delete'
            },
            {
                iconCls: 'edit'
            },
            {
                iconCls: 'delete'
            },
            {
                iconCls: 'edit'
            },
            {
                iconCls: 'delete'
            },
            {
                iconCls: 'edit'
            },
            {
                iconCls: 'delete'
            }, ,
            {
                iconCls: 'edit'
            },
            {
                iconCls: 'delete'
            },
            '->',
            '-',
            {
                iconCls: 'pdf',
                toggleGroup: 'documentPermission'
            },
            {
                iconCls: 'html',
                toggleGroup: 'documentPermission'
            }
        ]
    });

请帮助我

解决方案是在每个 Item 中添加 overflowText 属性，如下所示:

items: [
            {
                iconCls: 'delete',
                overflowText: 'delete'
            },
            {
                iconCls: 'edit',
                overflowText: 'edit'
            }
]

非常感谢-_-
