Subject Re: How to user logic:iterate[MORON]
Date Tue, 10 Sep 2002 14:40:39 GMT
I would like to thank everyone on this email list that helped out. Every
little bit helped including the property attribute on iterate and that
logic:present is very handy.
The main problem though was a complete brain fart on my part.
I am moron, hear me roar.
I forgot to include the tag lib import for logic. The thing I dont
understand is how it even go to the bean:write tag inside the iterate and
failed there?
Oh well, if you ever get an error message like I did, don't run around like
a chickend with your head chopped off, just include this line at the top of
the jsp...
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>

AAAAAAAAAAA, I hate stupid mistakes that waste everyone's time!!!
Mike
