First of all sorry if I have faults on my text, im low with English. I have a Table in a JSP that shows me people that is working on a patent.
Here you have the JSP code.
<c:forEach items="${newitem.inventors}" var="inv" varStatus="status">
<tr>
<input type="hidden" name='<c:out value="inventors[${status.index}].toDelete"/>' class="toDelete" value=''/>
<input type="hidden" name='<c:out value="inventors[${status.index}].id"/>' value='<c:out value="${inv.id}"/>'/>
<td><input type="text" name='<c:out value="inventors[${status.index}].nom"/>' value='<c:out value="${inv.nom}"/>'/> </td>
<td><input type="text" name='<c:out value="inventors[${status.index}].nif"/>' value='<c:out value="${inv.nif}"/>'/> </td>
<td><input type="text" name='<c:out value="inventors[${status.index}].departament"/>' value='<c:out value="${inv.departament}"/>'/> </td>
<td><input type="text" name='<c:out value="inventors[${status.index}].entitat"/>' value='<c:out value="${inv.entitat}"/>'/> </td>
<td><input type="text" name='<c:out value="inventors[${status.index}].relacioLaboral"/>' value='<c:out value="${inv.relacioLaboral}"/>'/> </td>
<td><input type="text" name='<c:out value="inventors[${status.index}].percent"/>' value='<c:out value="${inv.percent}"/>'/> </td>
<td class="inventorCheckBox">
<input type="checkbox"/>
<input type="hidden" class="textCheckBox" name='<c:out value="inventors[${status.index}].responsable"/>' value='<c:out value="${inv.responsable}"/>' />
</td>
<td><input type="text" name='<c:out value="inventors[${status.index}].mail"/>' value='<c:out value="${inv.mail}"/>'/> </td>
<td><input type="text" name='<c:out value="inventors[${status.index}].ordenacio"/>' value='<c:out value="${inv.ordenacio}"/>'/> </td>
<td><span onclick="deleteInventor(this);" style="margin-left:15px;font-size:1.4em;cursor:pointer;" aria-hidden="true" class="colorLogo icon-close"></span></td>
<!--<td class="inventorCheckBox">
<input type="checkbox"/>
<input type="hidden" class="textCheckBox" name='<c:out value="inventors[${status.index}].intern"/>' value='<c:out value="${inv.intern}"/>'/>
</td> -->
</tr>
</c:forEach>
Now im implementing the funcionality to ADD more people. Those people is stored on a HashSet to later introduce the data to the DataBase. First of all im trying to add people just copying 1 row with the element inspector and saving, but when I click to save it throws me this error.
