Angular UI Modal导致无限摘要循环

我一直在努力创建一个允许在模式弹出窗口中检索和打开文章的系统。它已经使用Bootstrap模式成功地实现了，但由于一些新的需求，我需要转换为使用Angular UI模式。

我认为这个问题源于Angular的$location.search（）对URL更改的处理，但我无法确定

由于添加了$uibModal.open（）调用，每当我点击一篇文章时，就会出现这个无限摘要循环，这将在我的控制器中启动openModal函数。

我将包括我的控制器代码和我在下面收到的错误消息。控制器的两个入口点位于$rootScope的底部附近$on和$scope$观看通话。它们允许模态响应URL中的更改。

最终目标是能够在URL更改时打开Angular UI模式，这样我就可以在模式被取消时删除URL参数。

谢谢你的帮助！

我的控制器：

(function () {
    'use strict';
    //Create the LinkModalController and bind it to the core app. This makes it always available.
    angular
        .module('app.core')
