Spring Boot with Thymeleaf #lists.contains() does not compare equal values

I'm trying to compare values in a select input to enable the selection selected="selected" of some elements.

I`m using: Spring Boot 1.4.0 and Thymeleaf 2.1.5

When I check if there are values I'm sure there are in a list, always returns false:

<p th:each="modulo : ${usuario.papeis}" th:text="${modulo.nome} + ' - ' + ${meusPapeis} + ' | ' + ${meusPapeis.contains(modulo.nome)}"></p>

Out:

ROLE_DASHBOARD - [ROLE_DASHBOARD, ROLE_USUARIO, ROLE_CONFIGURACOES] | false

Trying another approach:

<p th:each="modulo : ${usuario.papeis}" th:text="${modulo.nome} + ' - ' + ${meusPapeis} + ' | ' + ${#lists.contains(meusPapeis, modulo.nome)}"></p>

Out:

ROLE_DASHBOARD - [ROLE_DASHBOARD, ROLE_USUARIO, ROLE_CONFIGURACOES] | false

Really, I do not know what is the problem, because when I using a literal string the return is true:

<p th:each="modulo : ${usuario.papeis}" th:text="${modulo.nome} + ' - ' + ${meusPapeis} + ' | ' + ${#lists.contains(meusPapeis, 'ROLE_DASHBOARD')}"></p>

Out:

ROLE_DASHBOARD - [ROLE_DASHBOARD, ROLE_USUARIO, ROLE_CONFIGURACOES] | true

Is there any way to accomplish this kind of comparison, using variable value?

You should use the expressions utility #strings to convert to string with the method toString(stringToConvert). Enum is always confusing to use. Follow the documentation.

try #strings.toString(modulo.nome). It should works.
