Anyway, here is the full code:
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html-el"; prefix="html" %>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-logic-el"; prefix="logic" %>
<%@ taglib uri="http://java.sun.com/jstl/core"; prefix="c" %>
<html:html>
<body>
<%
java.util.ArrayList interests = new java.util.ArrayList();
java.util.HashMap map = new java.util.HashMap();
map.put("code","ABC");
interests.add(map);
request.setAttribute("interests",interests);
%>
<html:form action="interest">
<c:forEach var="interest" varStatus="loop" items="${interests}">
<html:checkbox indexed="true" property="${interest.code}"/>
</c:forEach>
</html:form>
</body>
</html:html>
The JSP scriplet fakes what normally happens in a action before getting to the JSP. Here is the exceptioin I get:
javax.servlet.jsp.JspException: indexed="true" is only valid within an
enclosing iterate tag
at org.apache.struts.taglib.html.BaseHandlerTag.prepareIndex(BaseHandlerTag.java:663)

Is it possible that this problem has something to do with me using resin? Guess I could download and setup tomcat to test...

Well it works fine for me - so I'm at a loss to explain. Maybe you should post the actual jsp code you are using - you said the jsp code looked like this:
<c:forEach var="item" items="${items}"> <html:text name="item" property="code"/> </c:forEach>
but the exception you show is for the EL version of the checkbox tag.
Also its better if you post to the struts user list rather than directly to me - someone who knows more than me or has experienced your problem may jump in if you post to the list.

Subject: Re: indexed="true" is only valid within an enclosing iterate tag
I am using Struts 1.1, I just copied jstl.jar, struts.jar and struts-el.jar into my project lib directory to be sure. Still getting the exception:
javax.servlet.jsp.JspException: indexed="true" is only valid within an enclosing iterate tag at
org.apache.struts.taglib.html.BaseHandlerTag.prepareIndex(BaseHandlerTag.jav a:663)
at org.apache.struts.taglib.html.CheckboxTag.doStartTag(CheckboxTag.java:188) at
org.apache.strutsel.taglib.html.ELCheckboxTag.doStartTag(ELCheckboxTag.java: 531)
I checked the source code around line 663 of BaseHandlerTag, here is what it looks like:
// Look for JSTL loops if (iterateTag == null) { Integer i = getJstlLoopIndex(); if (i != null) { index = i.intValue(); found = true; } } else { index = iterateTag.getIndex(); found = true; } if (!found) { // this tag should only be nested in iteratetag, if it's not, throw exception JspException e = new JspException(messages.getMessage("indexed.noEnclosingIterate")); RequestUtils.saveException(pageContext, e); throw e; }
Seems as though getJstlLoopIndex() isn't doing it's job, any ideas why? I have tried it with declaring the Loop Status in the c:forEach with varStatus="loop" and without, still get the exception.

Hmmm. The thinking behind my suggestion was "is jstl working properly
for
you or is the indexed thing just hinding some other root cause"
I'm out of ideas - the only other thing I can think of is what version
of
Struts are you using - I believe jstl was only catered for from Struts
1.1 -
so if you were using a version before that you would get the message
you're
seeing.

Yeah, if I remove the indexed="true", my JSP code looks like this:
<c:forEach var="item" items="${items}"> <html:text name="item" property="code"/> </c:forEach>
I get a bunch of HTML inputs like this:
<input type="text" name="code" value="ABC" />
With different values but all named code. Code is a property of item, and each item in items has a different code.

What happens if you remove the "indexed" attribute from all the <html:text> - does it work properly then (except for the "name"
attribute)
is the html page generated OK?

Subject: indexed="true" is only valid within an enclosing iterate tag
I am trying to use indexed properties in a form, as described in James Turner's Article "Succeeding With Struts: Indexed Properties and Beans as Properties" at
http://www.developer.com/java/ejb/article.php/2233591
The example shows you can use c:forEach with <html:text indexed="true"/>, like this:
<c:forEach var="lines" items="${purchaseOrderBeanForm.map.lines}" > <TR><TD><html:text indexed="true" name="lines" property="partNumber"/></TD> <TD><html:text indexed="true" name="lines"
property="quantity"/></TD>
<TD><html:text indexed="true" name="lines"
property="price"/></TD></TR>
</c:forEach>
But when I try to do that, I get this error:
indexed="true" is only valid within an enclosing iterate tag
Is my code wrong or is the example wrong?
