Re: Re[4]: EL Expression in html:hidden tag
Yup, that's the theory anyway. As of JSP 2.0 (with a Servlet 2.4 format web.xml
that has not explicity deactivated EL evaluation), request-time attribute values
can be specified using either the familiar scriptlet expression (<%= %>) or the
EL (${}). So, any pre-JSP 2.0 tags that have attributes with
true in their TLD file will automatically be able to
use the EL for request-time attribute values.

And run in a Servlet 2.4 / JSP 2.0 container of course ;-)
Not only will EL expressions work for attributes in any tag (as long as the
attribute accepts runtime expressions), it will also work in template text.
Consider a snippet like this to display a table of stuff from a list of
customer beans in a scoped variable named "customers":
Account Id
Customer Name
Total Sales
${customer.accountId}
${customer.name}
${customer.totalSales}
JSP 2.0 has lots of other cool things to, including the ability to point at a
chunk of JSP code and treat it just like a tag, without having to write
anything in Java.
