title: Bind fields from nested objects Thymeleaf
body: <p>We have to bind from a regular form made with Thymeleaf. We have a parent object with a nested object with some fields.</p>
  <p>We have put a select element like this :</p>
  <pre class="lang-html prettyprint-override"><code>&lt;select name=&quot;cumplirCiaps&quot;  th:onchange=&quot;|onChangueCumplirEpisodios(this);|&quot;&gt;
      &lt;option th:each=&quot;condicionEpisodios : ${radioCumplirTodosEpisodios}&quot;
                  th:text=&quot;${condicionEpisodios.descripcion}&quot;
                  th:value=&quot;${condicionEpisodios.codigo}&quot;
                  th:selected=&quot;${condicionEpisodios.codigo}&quot;
                  th:disabled=&quot;${modoConsulta != null}&quot;
                  th:field=&quot;${consultaCias.consultaExplotacionCupos.cumplirCiaps}&quot; /&gt;
  &lt;/select&gt;
  </code></pre>
  <p>We have to bind the value from the element we select in <code>cumplirCiaps</code> in the field from nested object. I put <code>th:field=&quot;${consultaCias.consultaExplotacionCupos.cumplirCiaps}&quot;</code> but when post this form and get value inside the method , we got null value. Anybody know solve this problem from the field in nested objects?</p>
