Problem with JSTL

[Melinda Savoy]

In my page I have the following tag:

 

At the top of my JSP page I have:

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>
<%@ taglib prefix="stripes" uri="http://stripes.sourceforge.net/stripes.tld" %>  

<stripes:submit class="button" name="saveAndSendTo"	id="sendTo"  value="Send"    [b][color=red]disabled="${!req.active || fn:length(req.reqItems) == 0}[/color][/b]" style="width: 55px; height: 23px; margin-left: 2px;"/>

 

I am getting an error that states:

Error: javax.el.ELException
Problems calling function 'fn:length'


Apparently I have my syntax wrong(?). Any help ASAP would be greatly appreciated. Thank you.

Sorry guys, I found my problem. The syntax was correct the object sent to the JSP page did not contains a req.reqItems property and that is the reason it bombed. I inserted a beginning and ending <c:choose...> <c:when...> tags and resolved my problem that way.

Thanks anyway. Regards.

Please look at your original post: see how what you thought would work didn't? It makes it *really* hard to even know what the question was.

I did notice that. Should the FONT and BOLD tags have gone on the outside of the original tags?

Thanks.

[David Newton]

They shouldn't be there at all.

OK. I was trying to point out where the problem was from a visual perspective. So I'll not do that in the future.
