Hi,
I'm beginner on struts 2. I want to display object properties by using
${...} in s:iterator tag. But It's not being rendered and ${name}
displaying. Is there any configuration that I missed?
*list.jsp*
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head></head>
<body>
<h1>User List</h1>
<ul class="nav nav-list todo-list">
<s:iterator value="#request.users" var="user">
<li id="user-<s:property value="#user.id"/>-${id}">
<span id="user-<s:property value="#user.id"/>-fullname"><s:property
value="fullname"/>**</span>
<span id="user-<s:property value="#user.id"/>-email"><s:property
value="email"/></span>
<s:if test="roles.length != 0">
<s:iterator value="roles" var="role">
<span id="user-<s:property value="#user.id"/>-role-<s:property
value="#role.id"/>" class="todo-category badge badge-info">
<s:property value="name"/>
</span>
</s:iterator>
</s:if>
</li>
</s:iterator>
</ul>

Hi Taner, I'm a beginner too. Isn't ${} evaluated as an expression
language expression? If so, the servlet engine should search an
attribute named id in the four scope (page,request,application,session).
To get a request parameter you might use the following el expression
${request.id} being request an implicit object in the page scope.
A useful tips to view the variable accessible with # or %{} sign is
inserting a tag <debug /> in the view page.
Waiting for an expert comment, anyway.
Best regards
