Я выполняю базовые упражнения во время изучения JSF 2.2 с аннотацией CDI, работающей на Tomcat 9. Журнал ошибок находится здесь:

Я запускаю страницу .xhtml с этим кодом:
<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://xmlns.jcp.org/jsf/html"
xmlns:f="http://xmlns.jcp.org/jsf/core">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Insert title here</title>
</head>
<body>
<f:commandLink action="#{conditionalNavigation.showPage}" value="Redirect to Convert page">
<f:param name="pageId" value="convert"></f:param>
</f:commandLink>
</body>
</html>
И этот класс .java:
package com.faire.jsf.tutorial;
import javax.enterprise.context.RequestScoped;
import javax.inject.Inject;
import javax.inject.Named;
@Named
@RequestScoped
public class ConditionalNavigation {
@Inject
private String pageId;
public String getPageId() {
return pageId;
}
public void setPageId(String pageId) {
this.pageId = pageId;
}
public String showPage() {
if (pageId == "convert") {
return "convertNumberDate";
} else {
return "conditionalnavigation";
}
}
}
Я попытался выполнить поиск в Google / search stackoverflow, но безрезультатно - я не понимаю, в чем заключается ошибка. Указывает ли @Default на .xhtml страницу, в которой вводится параметр без спецификатора? Какую ошибку я делаю?
