1.向后台传数据时，当server-side-controller方法中接收的参数为sobject的列表时，在需要在前台上传列表的每个对象中设置：

object['sobjectType'] = '指定的sobjet对象类型如:Project__c';

2.在需要触发event的时候，每次使用component.getEvent('Event Name')获取的event只能被触发一次，否则会报错：event has been fired. 

// wrong example
({
    init: function (cmp, event, helper) {
        var event = cmp.getEvent('{event name}');
        cmp.addEventHandler('{event name}', function (e) {
            event.fire(); // the first time can fire the event, but the second time can't
        })
    }
})
// right example
({
    init: function (cmp, event, helper) {
        cmp.addEventHandler('{event name}', function (e) {
            // every time when need to fire a event, first to get it.
            var event = cmp.getEvent('{event name}');
            event.fire();
        })
    }
})

3.当客户端controller获取以自定义的Apex Class返回的结果时，必须使用@AuraEnable 标注Class的每个需要被获取的成员属性。否则在前台获取的每个对象都是空对象。
