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?
