Thank you Dave,
Let me show you the generated HTML file :
<body>
<table>
<form name="pageForm" method="post" action="/EssaiA/traitement.do">
<tr>
<td>Nom</td>
<td><input type="text" name="liste[0].nom"
value="1"></td>
<td>Prénom</td>
<td><input type="text" name="liste[0].prenom"
value="0"></td>
</tr>
<tr>
<td>Nom</td>
<td><input type="text" name="liste[1].nom"
value="9"></td>
<td>Prénom</td>
<td><input type="text" name="liste[1].prenom"
value="2"></td>
</tr>
.....
</body>
We see the indexed liste (liste[0], liste[1], ...).
So, what may I do to indicate that form contains an indexed property ? In which
file(s) ?
