Javascript angularJS重复错误

我尝试在一些更改之后刷新数据，但我得到的只是ng repeat中的重复错误

情况是,

我尝试构建一个动态菜单模块

您需要添加、删除、更改顺序并分配给不同的主菜单项等

除了在表中重新加载菜单结构外，其他一切都可以正常工作

我清除了原始对象，表卸载并没有显示任何数据，然后我尝试以更改后的形式重新加载数据，出现dupes错误。重新编辑浏览器后，所有内容都会按原样更新并正确显示，直到下一次更新

由于缩进和顺序可能会改变，我无法真正推动和拼接阵列

代码

模块

"use strict";
// no dependencies
angular.module('appWebmenu', []);

主要指令

'use strict';

angular.module('appWebmenu').directive('appWebmenu',function() {
    return {
        scope:false,
        controller: 'appWebmenuController',
        templateUrl: 'external/appWebmenu/appWebmenuTemplate.html'
    };
});

List指令将实际表的作用域移动到模块控制器

angular.module('appWebmenu').directive('appWebmenuList', function() {
    return {
        transclude: true,
        templateUrl: 'external/appWebmenu/appWebmenuListTemplate.html',

我尝试过按$index跟踪、按数组中的某个唯一项（menu_id）跟踪等方法，但这并没有什么区别，或者实际上使情况变得更糟

我希望有人能帮我解决这个问题。
