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?

I meant

Re: indexed="true" is only valid within an enclosing iterate tag
Posted by Paul Barry <pa...@nyu.edu>.
If I do this:
<c:forEach var="item" varStatus="loop" items="${items}">
<html:text property="items[${loop.index}].code"/>
</c:forEach>
It gives me the results I want:
<input type="text" name="interests[0].code" value="ABC" />
<input type="text" name="interests[1].code" value="BCD" />
...
But I can't get indexed="true" to work with c:forEach

Re: indexed="true" is only valid within an enclosing iterate tag
Posted by Niall Pemberton <ni...@blueyonder.co.uk>.
Well I'm out of ideas. I can get this error with this jsp code if I removed
the <@ taglib> definition for c.tld - but you have it in your jsp and if the
tld was a problem you wouldn't see the <c:forEach> working when you remove
the indexed="true" attribute.
Obviously its something in your environment but I don't know whats not
right - its got to be something to do with either Struts, JSTL or the
servlet container your using thats either the wrong version or not
configured properly.

Re: indexed="true" is only valid within an enclosing iterate tag
Posted by Paul Barry <pa...@nyu.edu>.
Sorry if this is confusing, I'll explain what I am trying to do. I want
to give the use a form with a number of "interests" and I want to track
which ones they check off. The way I thought to do it is have a form
with a List property called interests. I would have an action
prepopulate the interests property with Interest objects. I guess the
Interest object would have to have a boolean "selected" property that is
initially set to false, which would make all the options appear
unchecked, and then when the user submits the form to a different
action, I would store the interests in the database where selected is
true. Is that how you normally handle an indexed property like this? I
haven't really gotten very far in figuring this out yet because of the
problem with the indexed attribute.
I just made up this JSP example because it illustrates the point that no
matter what I do, I seem to get the "must be in an interate tag"
exception. I put your code into my jsp page:
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html" %>
<%@ 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);
%>
<c:forEach var="interest" items="${interests}">
<p>Interest: <html:text indexed="true" name="interest"
property="code"/></p>
</c:forEach>
</body>
</html:html>
Still get the same exception.

Re: indexed="true" is only valid within an enclosing iterate tag
Posted by Niall Pemberton <ni...@blueyonder.co.uk>.
No worries. Your stuff's a bit confusing. On your <html:form> you have an
action named "interest" and you don't specify a "name" attribute on your
<html:checkbox>. That means the checkbox tag is going to try and get the
form associated with your "interest" action (if it doesn't exist, it'll try
and create it) and then try to retrieve the property you named which is
"${interest.code}", plus the fact you are storing a "interests" object in
request scope.
I changed your code and the following worked for me, the only difference is
I don't use the "el" versions of the struts tags - just the standard ones:
<%
java.util.ArrayList interests = new java.util.ArrayList();
java.util.HashMap map = new java.util.HashMap();
map.put("code","ABC");
interests.add(map);
request.setAttribute("interests",interests);
%>
<c:forEach var="interest" items="${interests}">
<p>Interest: <html:text indexed="true" name="interest"
property="code"/></p>
</c:forEach>
... and it produced:
<p>Interest: <input type="text" name="interest[0].code"
value="ABC"></p>

Re: indexed="true" is only valid within an enclosing iterate tag
Posted by Paul Barry <pa...@nyu.edu>.
Sorry for replying directly to you Niall. I meant to reply to the whole
list. I think when you reply to a message you are replying to the user
list and me individually, because I get two copies of each message that
you post. The reply-to on one of them it set to the struts user list,
and the reply-to on the other is set to your address, so I guess I
replied to the wrong one.
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:

enclosing iterate tag

Is it possible that this problem has something to do with me using

Re: indexed="true" is only valid within an enclosing iterate tag
Posted by Niall Pemberton <ni...@blueyonder.co.uk>.
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.

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.

Re: indexed="true" is only valid within an enclosing iterate tag
Posted by Paul Barry <pa...@nyu.edu>.
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?
