html:link and collection

[Francisco Exposito Aguilera <fc...@hotmail.com>]

Hi,

I have a jsp where I show some fields of a search. If I click on every row, 
I must be redirected to a new page with all info of that row. As I read 
weeks ago at this mailing list, it should be done with html:link, but I have 
some problems...

The DispatchAction searchUsers which "show" the page with some fields of all 
rows:

request.getSession().setAttribute("listUsers",users);

The jsp result after that action:

<c:forEach items='${listUsers}' var='lee'>
    <tr>
        <td><c:out value='${lee.dni}'/></td>
        <td><c:out value='${lee.name}'/></td>
        <td><html:link action="searchUsers.do?parametro=editUser" 
paramName="listUsers" paramId='${lee.dni}'>
        Editar	</html:link></td>
    </tr>
</c:forEach>

In the editUser dispatchAction:

Collection usuarios = 
(Collection)request.getSession().getAttribute("listarUsuarios");
String a = request.getParameter("dni");

The collection usuarios get the correct info, but the string a obtain null.

What am I doing wrong?

Thanks a lot
