YOU 'DA MAN!
I forgot something so *&@# simple! As soon as I added the taglib directive,
I was able to successfully iterate.
Thanks so much for hanging on and helping me out..

Aaron,
Lets go back to your second error, the
"javax.servlet.ServletException: Cannot find bean task in scope null".
I can simulate this if, in one of the pages where I use an iteration in
this manner, I remove or modify the tag definition. Are you absolutely
sure that you have the
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
tag definition in your page? and that the prefix "logic" is the same in
the tag definition? This would account for "workman" being printed only
once and getting a null pointer when you refered to the "task" iteration id.
