JSF教程(8)——生命周期之Apply Request Values Phase
当一个组件tree在一个postbacks请求中被恢复之后其中每个组件从request的参数中取得各自的值,这里使用的是processDecodes方法。这个值会保存在本地的每个组件中,在源码中此过程的代码较为简单,因为实现者将取值这个操作全部封装在processDecodes方法中。不过说实话JSF的这部分的实现非常失败,因为在UIViewRoot中有将近两千行代码,这,这,这……...

JSF教程(10)——生命周期之Update Model Values Phase
在整个JSF生命周期中经历了取值、验证的阶段最终从request中拿到合理的值,下面就是在本阶段给相应的服务端对象(ManageBean)赋值了。JSF实现只是去更新和input组件中value属性对应的bean的属性的值,也就是说如果在界面上没有讲ManageBean的属性“绑定”到Input类的组件中那么这个Bean的属性是不会更新的。这里需要留意的是如果本地的数据不能转化为对应Bean的属性...
