Question

我在尝试使用Liferay Faces和任何JSF组件来触发动作事件时遇到问题。

我已经完成了Liferay的Developing JSF Portlets指令页的第一部分，直到（但不包括）Internationalize JSF Portlets部分成功。我继续并添加了一些其他JSF组件也取得了一些成功，但事件并没有起作用。

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，文本区域将通过AJAX在每次击键时更新“Hello，XXX”（其中XXX是文本）从箱子里）。是的，在一个单独的JSF项目中，我尝试了view.xhtml和TestBean.java，它可以工作。

在Liferay门户中，portlet显示，当我输入时，我收到回发到服务器。 DebugPhaseListener仅在RESTORE_VIEW 1之前/之后，在RENDER_RESPONSE之前或之后产生6.中间没有相位，我认为这表示问题。（注意：Liferay Faces portlet桥接桥接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Liferay最新的Tomcat软件包以及来自Liferay更新站点的最新eclipse插件。 Java 1.7.0_71。

以下是我认为与确定正在发生的事情相关的所有资产和代码。您将给予的任何帮助将不胜感激。

Answer 1

请将以下内容添加到 <portlet> 的WEB-INF/liferay-portlet.xml部分：

<requires-namespaced-parameters>false</requires-namespaced-parameters>

确保遵循DTD并按正确的顺序包含元素：https://docs.liferay.com/ce/portal/7.0-latest/definitions/liferay-portlet-app_7_0_0.dtd.html。

例如，您的 liferay-portlet.xml <portlet>部分应如下所示：

<portlet>
    <portlet-name>my-calendar-portlet</portlet-name>
    <icon>/icon.png</icon>
    <requires-namespaced-parameters>false</requires-namespaced-parameters>
    <ajaxable>false</ajaxable>
    <header-portlet-css>/css/main.css</header-portlet-css>
    <footer-portlet-javascript>
        /js/main.js
    </footer-portlet-javascript>
    <css-class-wrapper>
        my-calendar-portlet-portlet
    </css-class-wrapper>
</portlet>

为什么Liferay Faces不处理JSF portlet动作事件？
