I've tried but doesn't work.. if I try to render the url with a dynabean accessor
(a_nomefile or
others) I get an error, the out tag works fine instead.
I'm using JSTL on Resin 2.1.5 + Linux
500 Servlet Exception
javax.servlet.jsp.JspException: An error occurred while evaluating custom
action attribute "value" with value "${item.a_nomefile}": Unable to find
a value for "a_nomefile" in object of class
