我在尝试使用 Liferay Faces 以及任何 JSF 组件来触发动作事件时遇到问题。
我已经完成了 Liferay 的开发 JSF Portlets指令页面的第一部分,直到(但不包括)成功国际化 JSF Portlets 部分。我继续并添加了一些其他 JSF 组件,也取得了一些成功,但是,事件不起作用。
此示例的目标是有一个文本框,用户可以在其中更改“World”的默认文本,并且文本区域将在每次击键时通过 AJAX 更新“Hello, XXX”(其中 XXX 是框中的文本)。是的,在一个单独的 JSF 项目中,我尝试了 view.xhtml 和 TestBean.java 并且它可以工作。
在 Liferay 门户中,portlet 显示出来,当我键入时,我得到了一个回发到服务器的信息。DebugPhaseListener 只导致 BEFORE/AFTER RESTORE_VIEW 1 和 BEFORE/AFTER RENDER_RESPONSE 6。两者之间没有阶段,我认为这表明存在问题。(注意:Liferay Faces Portlet 桥接 Portlet 生命周期事件并模拟 JSF 生命周期。)
我正在使用 Liferay 6.2,在 Eclipse Luna 中运行,带有 Liferay 最新的 Tomcat 包和来自 Liferay 更新站点的最新 eclipse 插件。Java 1.7.0_71。
以下是我认为与弄清楚发生了什么相关的所有资产和代码。您可以提供的任何帮助将不胜感激。
