In the absence of a taglib directive, what looks to you like a Struts tag just looks like template text to the compiler, and it is simply passed through to the response (like all the non-tag HTML markup in a typical Struts-based JSP page). Remember, there is no requirement that the template text look like HTML or XML markup, so there is absolutely no basis on which the compiler can possibly consider this to be an error condition. > > --joe Craig -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>

wow, really!? The JSP compiler doesn't even issue a warning? That's pretty lame.

Re: How to user logic:iterate[MORON]
Without the taglib statement, the tag is completely ignored, as if it
wasn't there. The JSP service assumes it's a HTML tag, and the browsers
silently swallow anything they don't understand. C'est la vive.

Re: How to user logic:iterate[MORON]
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" %>
AAA, I hate stupid mistakes that waste everyone's time!!!
Mike
