T. Hedersen の backbone.validation プラグイン ( https://github.com/thedersen/backbone.validation ) をモデル バインディング用の backbone.stickit プラグインと組み合わせて使用​​しています。モデルの単一の属性が変更されたときにすべてのフィールドを常に検証するという奇妙なエラーが発生しています。ここにコードがあります

モデル

define(function(require) {

    "use strict";
    var $ = require('jquery'),
            Backbone = require('backbone'),
            Validation = require('backbone.validation'),
            applicantModel = Backbone.Model.extend({
        defaults: {
            firstName: '',
            middleName: '',
            lastName: ''
        },
        initialize: function() {
        },
        validation: {
            firstName: {
                required: true
            },
             middleName: {
                required: true
            },
            lastName: {
                required: true
            }

        }
    });

    return new applicantModel;
});

モデルのデフォルト値を '' に設定しないでください。可能であれば、デフォルト値を削除してください。
