我想使用HtmlDataTable的navigateToRow（）和findRow（）方法从数据表中选择一个特定的行。我按照这个链接 http://component-showcase.icesoft.org/component-showcase/showcase.iface ==＆gt;表格==＆gt;查找行选项。我正在将数据表绑定到辅助bean。我得到以下错误“方法findRow（String，String []，int，String，boolean）未定义类型HtmlDataTable”在我使用findRow（）和navigateToRow（）方法的行。如何解决这个错误。
这是我的jspx页面
