<li {#ctx.httpSession} >
                      <span th:object="${session.user}"> </span>
                      <span><p>Surname: <span th:text="*{user.id}">Pepper</span></p></span>

This is one of my attempts
<li sec:authorize="isAuthenticated()" {#ctx.httpSession}, th:object="${session.user}"  th:replace="::menuItem ( '/users/'+*{user.id}+'/coworkers/find','coworkers','find coworkers','search','Find coworkers')"><span>Find Coworkers</span>
                  </li>
This is the orginial
<li sec:authorize="isAuthenticated()"  th:replace="::menuItem ( '/users/2/coworkers/find','coworkers','find coworkers','search','Find coworkers')">
