                        ```<select th:field="*{role}">
                            <option value="#" disabled = "disabled" selected="selected">Role...</option>
                            <!--<option th:each="r : ${roles}" th:value="${r}" th:text="${r.name}">Developer</option>-->
                            <option th:each="r : ${roles}" th:value="${r.id}" th:text="${r.name}">Developer</option>
                        </select>```

I am getting this error:

Field error in object 'collaborator' on field 'role': rejected value [33]; codes [typeMismatch.collaborator.role,typeMismatch.role,typeMismatch.com.imprender.instateam.model.Role,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [collaborator.role,role]; arguments []; default message [role]]; default message [*Failed to convert property value of type 'java.lang.String' to required type 'com.imprender.instateam.model.Role' for property 'role'*; nested exception is java.lang.IllegalStateException: Cannot convert value of type 'java.lang.String' to required type 'com.imprender.instateam.model.Role' for property 'role': no matching editors or conversion strategy found]

I says: Failed to convert property value of type 'java.lang.String' to required type 'com.imprender.instateam.model.Role' for property 'role'

but I don't understand where I am doing that...
