Question

我在_id字段上使用自定义验证，如下所示。首先，我输入一个ID并点击提交，它将保留在数据库中。下次，我重用相同的ID并尝试提交，我收到验证错误。我再次点击提交按钮，我在chrome日志中抛出一个奇怪的内部服务器错误。验证错误消失并感觉好像表单已成功提交，但实际上并非如此。我无法弄清楚为什么会在第二次尝试时发生这种情况。通常，验证错误必须一次又一次地出现，我点击提交的次数。我做错了什么？

架构：

id":{
        type:String,
        label: "Template Name",
        unique: true,
        autoform:{
            textHelp:"Unique name to identify the template"
        },
        custom: function() {
            if (Meteor.isClient && this.isSet) {
                Meteor.call("isAggrUnique", this.value, function(error, result) {
                    if (!result) {
                        aggrRouter_aaaContext_template_collection.simpleSchema().namedContext("aggrRouter_aaaContext_template_form").addInvalidKeys([{
                            name: "_id",
                            type: "notUnique"
                        }]);
                    }
                });

            }
            if (Meteor.isServer) {
                Meteor.methods({
                    isAggrUnique: function(id) {
                        return aggrRouter_aaaContext_template_collection.find({
                            _id: id.toUpperCase()
                        }).count() === 0;
                    }
                });
            }
        }
    },

多次提交后，Chrome开发日志会显示：

aldeed_autoform.js?hash=9676200…:7782 errorClass {error: 500, reason: "Internal server error", details: undefined, message: "Internal server error [500]", errorType: "Meteor.Error"}

Meteor服务器日志显示：

为什么说我不止一次定义isAggrUnique？
