我是 JSF 的新手，我正在构建一个使用 facelets 创建的应用程序。
这是我的模板
master.xhtml

现在，当我运行此代码（实际上是 masterp.xhtml）时，它会显示完美的输出并准确加载，但会在控制台中引发异常，即

我认为因此它没有提交我的按钮的操作
<h:commandButton id="btnMasterSearch" type="submit" value="Search" styleClass="submitButton" action="#{masterSearch.findPerson}">出现在MasterSearch.xhtml。我在 SO 上发现人们有这个问题，但我无法找到并理解一个好的解决方案。
请帮忙谢谢
