Re: How to run an iterator twice in a page
Please ignore this topic as the problem was due a typo in my jsp. I apologize for wasting your time on an issue that is not a problem, I should have checked more carefully.
regards,

Subject: Re: How to run an iterator twice in a page
I was hoping to find a better way to do this for a case as simple as the this one rather than resorting to hacks. Normally in JSTL when c:foreach is used a new iterator is created. I also tried the following in the second iterator but of no avail
<s:iterator value="[1].users" id="u" status="status">
I also tried to move users into request scope [ <s:set id="users" name="users" scope="request" value="users"/>] and then try
<s:iterator value="#request.users" id="u" status="status">
in both iterators, But only the first table is displayed.

It's sort of "hack-ish", but can you make a copy of the list of users in the Java code, and iterate over the copied list for the 2nd set of results?

Subject: How to run an iterator twice in a page
I have a list of users and I would like to iterate over this list twice in a page. However in the following code snippet, The list is iterated only once and the second iterator displays nothing.
<p>Table 1</p>
<table cellspacing="1" cellpadding="0" class="basic-table" width="100%">
<tr class="gray-med-dark">
<th nowrap="nowrap" scope="col">user id</th>
<th nowrap="nowrap" scope="col">user name</th>
</tr>
<s:iterator value="users" id="u" status="status">
<tr >
<td><s:property value="#u.id" /></td>
<td><s:property value="#u.name" /></td>
</tr>
</s:iterator>
</table>
<p>Table 2</p>
<table cellspacing="1" cellpadding="0" class="basic-table" width="100%">
<tr class="gray-med-dark">
<th nowrap="nowrap" scope="col">user id</th>
<th nowrap="nowrap" scope="col">user name</th>
</tr>
<s:iterator value="users" id="u" status="status">
<tr >
<td><s:property value="#u.id" /></td>
<td><s:property value="#u.name" /></td>
</tr>
</s:iterator>
</table>
In the second iterator I even renamed the id to u1 but of no avail. I think in the first iterator all the user objects are pushed on the top of stack hence users is not availabe on the second iterator. I would appreciate any hints on how to achieve this.

That wasn't your only error. Remember, having more than one item on a
single (x)html page with the same id is illegal and may result in
unexpected behaviors.
