Tracker重新计算功能的例外情况

Question

我有一个模板助手访问我的应用程序中的集合.但我已关闭反应性:

Template.homeBoxGroupsTpl.helpers({
    boxes: function () {
        return Boxes.find({},
            {
                sort: {
                    order: 1
                },
                reactive: (Session.get("homeCanvasTplReactive") || false)
            }
        );
    }
});

在我的页面上插入一个新元素后,它会更新集合,Meteor将在浏览器控制台中抛出一个错误:

    Error: Exception from Tracker recompute function: reporters.js?1429904535194:67

任何想法如何调试,或者它是一个流星问题？

Answer 1

Meteor 的错误消息在除 Chrome 之外的所有浏览器中都很可怕，因为 Meteor 期望堆栈跟踪包含错误消息，但这只有 Chrome 才能完成。我不想这么说，但在调试 Meteor 应用程序时您可能必须使用 Chrome。:(
