RE: puzzled with id
Apologies to the community. The
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
was missing.
On the other hand, it is an ugly issue that is raised here: How much
encapsulation should one provide?
In this case, how come a lack of declaration, as in not importing a
whole library, does not shout for a different type of exception? It is
more of an error than a runtime exception.

Good point but that is the intended behavior. Good is a composite bean
that holds the good itself and other stuff hence the description another
level deep as in item[0].getGood().getDescription() as you pointed out
correctly.
I tried your suggestion anyhow with the same result. I also tried to
render one atomic field only from item as in:
with same resulting exception. I can't figure out why 'item' is out of
scope

Hey. It looks like the problem is in your propery attribute.
property="good.description" is equivalent to calling
item[0].getGood().getDescription(). Try just property="description".

hi all,
Like all developers, I am trying to figure out why things aren't
happening.
my jsp uses an iterate tag.
good description:
I assume "item" is a local variable constructed to hold elements from
the java.util.List goods from the form in scope. So I suppose, it oculd
be anything. However, when trying to render its properties, I get an
error even when specifying its type:
javax.servlet.ServletException: Cannot find bean item in scope null at
org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContex
tImpl.java:457)
On the other hand, this java code works fine:
<%
SubmitForm myform = (SubmitForm)(request.getAttribute("submitForm"));
java.util.List goods = myform.getGoods(); PABean pabb =
(PABean)(goods.get(0));
out.print("good description = "+pabb.getDescription());
%>
Are there extra steps I am missing? (I am using JBoss w/catalina)
