render属性提供对Ajax交互后需要更新的页面上的一个或多个组件的引用。

你需要在你的项目中找到＆＃34; render＆＃34;的价值。（JSF表达语言）

您可能想要自己参考这些或谷歌 - https://stackoverflow.com/a/12404888/1193815 http://www.tutorialspoint.com/jsf/jsf_ajax.htm https://docs.jboss.org/richfaces/latest_4_0_X/Component_Reference/en-US/html/chap-Component_Reference-Common_Ajax_attributes.html#sect-Component_Reference-Common_Ajax_attributes-Rendering
