我正在将一个初始项目从 PrimeFaces 2.2.1 迁移到 3.3.1，遵循MigrationGuide的步骤并使用3.3 版本的用户指南。
我想要一个p:dialog在页面顶部，包含导航。当我单击页面顶部的链接时，必须显示此对话框。
错误描述：
当我单击“我想要”链接时，页面上什么也没有发生（p:dialog 没有显示），并且我在 Firebug 的控制台上收到此错误：
popupModalMenu is not defined http://localhost:8080/{appname}/view/xhtml/principal.jsf Line 1p:dialog (id= " modalMenu") 在页面上加载。
结构如下：
