thymeleaf security tags not being displayed, either with authenticated or anonymous access

Question

In my current spring project, I have a view with this code:

      <ul class="nav navbar-nav navbar-right" sec:authorize="isAnonymous()">
        <li><a th:href="@{/signin}" th:utext="#{signin}"></a></li>
        <li><a th:href="@{/signup}" th:utext="#{signup}"></a></li>
     </ul>
     <ul class="nav navbar-nav navbar-right" sec:authorize="isAuthenticated()">
        <li><a th:href="@{/cart}"><span class="glyphicon glyphicon-shopping-cart" aria-hidden="true"></span></a></li>
        <li sec:authorize="hasPermission(#user, 'admin')"><a th:href="@{/admin}"><span class="glyphicon glyphicon-cog" aria-hidden="true"></span></a></li>
        <li class="dropdown">
            <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false"><span sec:authentication="name">Teste</span> <span class="caret"></span></a>
            <ul class="dropdown-menu">
                <li><a href="#"><span class="glyphicon glyphicon-user" aria-hidden="true"></span><span th:utext="#{myaccount}"></span></a></li>
                <li><a href="#"><span class="glyphicon glyphicon-heart" aria-hidden="true"></span><span th:utext="#{mywishlist}"></span></a></li>
                <li><a href="#"><span class="glyphicon glyphicon-briefcase" aria-hidden="true"></span><span th:utext="#{myorders}"></span></a></li>
            </ul>
        </li>
        <li><a th:href="@{/logout}"><span class="glyphicon glyphicon-off" aria-hidden="true"></span></a></li>
      </ul>

When I open the page in the browser, nothing is displayed, neither the tags marked with sec:authorize="isAnonymous()" or the ones marked with sec:authorize="isAuthenticated()".

My configuration is this:

</beans>

Can someone give a hint of what's the problem here?

ps.: this is my pom.xml regards the thymeleaf dependencies:

<dependency>
    <groupId>org.thymeleaf</groupId>
    <artifactId>thymeleaf</artifactId>
    <version>2.1.5.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.thymeleaf</groupId>
    <artifactId>thymeleaf-spring4</artifactId>

</dependency>

Answer 1

I finally solve this on my own. The problem here was with this line I had on my XML configuration file:

<security:http pattern="/" security="none"></security:http>

After I remove it, both conditions start to work fine. Seems like with this line, the security context completely stop work on this web page.
