hi all.
i have in my DynaValidatorForm called entrantesForm, declared an ArrayList (called
colRequetes) of RequeteTO objects.
<form-property name="colRequetes" type="java.util.ArrayList" /></form-bean>
in my jsp, i want to update some properties of RequeteTO, like 'typeRequete' with the
html-tag(html-el taglib declared above) with the <html:selec>t tag.
<c:forEach items="${entrantesForm.map.colRequetes}" var="enregistrement"
varStatus="status">
<c:set var="numero" value="${status.index}" scope="page" />
<tr>
<td><html:radio property="id" value="${enregistrement.id}" /></td>
<td><c:out value="${enregistrement.nomRequete}" /></td>
<td><c:out value="${enregistrement.typeObjet}" /></td>
<td><html:select size="1" name="colRequetes" property="typeRequete"
indexed="true" value="${enregistrement.typeRequete}" >
<html:option value="Publique" >
<c:if test="${enregistrement.typeRequete ==
'Publique'}"><c:out value="${enregistrement.typeRequete}" /></c:if>
</html:option>
<html:option value="Privée" >
<c:if test="${enregistrement.typeRequete == 'Privée'}"><c:out
value="${enregistrement.typeRequete}" /></c:if>
</html:option>
</html:select >
</td>
</tr>
</c:forEach>
the jsp result is good.
an extract of the html source producted by the jsp:
<form name="entrantesForm" method="POST"
action="/comsis/entrantes/EntrantesRequete.do">
<table>
<tr>
<th></th>
<th>Nom de la requete</th>
<th>Type dossier</th>
<th>Type requete</th>
</tr>
<tr>
<td><input type="radio" name="id" value="13" checked="checked" /></td>
<td>s</td>
<td>entrante</td>
<td><select name="colRequetes[0].typeRequete" size="1"><option value="Publique"
selected="selected">Publique</option>
<option value="Privée">Privée</option></select>
</td>
</tr>
<tr>
<td><input type="radio" name="id" value="15" /></td>
<td>gbgh,gh</td>
<td>entrante</td>
<td><select name="colRequetes[1].typeRequete" size="1"><option
value="Publique">Publique</option>
<option value="Privée" selected="selected">Privée</option></select>
</td>
</tr>
</table>
but, when i submit the form,
the server says that:
