You know your stuff hey :)
I believe I do use Tomcat 5 (running inside JBoss 3.2) and as a result
have
their JSTL (looks like 1.1) and JSP-2.0.jar. Where do I find or can I
check
if I have the TLD for the functions library (so I can include it if
missing)? At the moment I am including the TLD's in my WAR project and
specify them in the web.xml file.
Thanks again.

I suspect that you are using either Tomcat 4.1.x and / or Standard 1.0x
for your JSTL. EL functions are part of the JSTL 1.1 spec (JSP 2.0)
and aren't supported on Tomcat 4.1.x or Standard 1.0x (JSP 1.2 and JSTL
1.0 respectively). If you want to use the fn:length you need to use
JSTL 1.1 and hence Standard 1.1 and / or Tomcat 5.x. (I think those
versions are correct, someone correct me if I'm wrong).
If you cant change the version of Tomcat / JSTL you use:
1. You could alter your myController.getOpenActivitiesForResource
method to return a class that extends list to provide a getSize() (and
hence your original <c:out value="${myList.size}"/> would work.
2. Find some other Tag lib that lets you output list sizes.
(unstandard from the sandbox does this)
3. Just use a scriptlet <%= ((MyControllerClass)
pageContext.findAttribute("myController")).getOpenActivitiesForResource
(
).size() %>.
