Hello guys
i have this case:
for payments each object (a debt) can has more details about part of payment
(Set object) of the object
so, in the next part of code jsp,
the first for represents the list of the objects and the nested for (second)
represents the details or the Set objects for each Object of the first for
all the objects and its details are already initializated by hibernate , so
<% //HIJOS DE LOS HIJOS %>
<c:forEach items="${hijosCorrienteProveedoresHijosHijos}" var="hijo"
varStatus="status" >
<c:set var="permission" value="${status.count +1}"/>
<tr id="trid<c:out value="${permission}"/>">
<input type="hidden" id="idCuentaProveedores<c:out
value="${permission}"/>" value="<c:out
value="${hijo.idCuentaProveedores}"/>" />
...... more
</tr>
<% //LOS SUBHIJOS %>
<c:forEach items="${hijosCorrienteProveedoresHijosHijos.cuentaProveedores}"
var="mihijo" varStatus="status" >
<c:set var="subcount" value="${status.count +1}"/>
<tr id="trid<c:out value="${permission}"/>".<c:out
value="${subcount}"/>">
<input type="hidden" id="idCuentaProveedores<c:out
value="${permission}"/>".<c:out value="${subcount}"/>" value="<c:out
value="${mihijo.idCuentaProveedores}"/>" />
<td><input type="text" id="numrow<c:out value="${permission}"/>".<c:out
value="${subcount}"/>" value="<c:out value="${permission}"/>".<c:out
value="${permission}"/>" size="15" readonly="true"/></td>
..... more
</tr>
</c:forEach>
</c:forEach>
<c:forEach items="${hijosCorrienteProveedoresHijosHijos.cuentaProveedores}"
var="mihijo" varStatus="status" >
in the bold part i recieve this error message
