Subject Re: Problem when a use a x:forEach into another x:forEach

Hi Rashmi,

Thank you for the answer.

Have you been able to reproduce the error?  Is my syntax wrong (I'm not
thrill by Node context :-) ?

Even if a try to use a <c:catch> block, I got no error.  (I still have to
look in the error log thou, first think Monday morning).

1) By using  Servlet 2.4 jar, you mean are we using a Servlet
2.4container?  If so, yes.

2) I already change the web.xml file to use servlet 2.4

3) I use a local version  (I made sure the .tld file are the one coming with
the taglibs JSTL 1.1 package.) of the taglibs declaration.

So I use:

<%@ taglib prefix="c" uri="/WEB-INF/c.tld" %>
<%@ taglib prefix="x" uri="/WEB-INF/x.tld" %>

instead of:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="x" uri="http://java.sun.com/jsp/jstl/xml" %>

If a try the latest, I got a error.  (Is it only namespace or some firewall
may be blocking those???)

Once again, thank you
