I have some problems concatenating 2 values in thymeleaf



I do the following:



<tr th:each="p , in: ${info}">

<td th:utext="${p.nombre}">...</td>

<td th:utext="${p.preferencias.get(0).getNombrePref()} +'-'+ ${p.preferencias.get(1).getNombrePref()}">...</td>

<td th:utext="${p.email}">...</td>

</tr>


This is how the page looks like



As you can see this is not dynamic because if p.preferencias size is bigger than 2 this will be a problem and the same if is less than 2



this what i tried :



<tr th:each="p , in: ${info}">

<td th:utext="${p.nombre}">...</td>

<td th:each="a , arcd : ${p.preferencias}" th:utext="${p.preferencias.get(arcd.index).getNombrePref()}">...</td>

<td th:utext="${p.email}">...</td>

</tr>


This is what i got:



And got this



As you can see the second value move to email :( then i thought in concat the values and try this :



<tr th:each="p , in: ${info}">

<td th:utext="${p.nombre}">...</td>

<td th:each="a , arcd : ${p.preferencias}" th:utext="${p.preferencias.get(arcd.index).getNombrePref()} + '-' +${p.preferencias.get(arcd.index).getNombrePref()} " >...</td>

<td th:utext="${p.email}">...</td>

</tr>


And this is the result:



Result 3



I dont know how to concat the values and keep those in one cell
How can i execute the loop to get all the values inside p.preferencias variable ?



EDIT:
post wrong image in result 3 now is the correct image
