Subject EL - access to nonexisting property, but no error ?
Date Wed, 26 Aug 2009 11:32:55 GMT
versions: Tomcat 5.5.28, Java "1.6.0_15" and Windows XP Pro SP3

Hi!

Can someone explain why does an EL like "${someListobject.a}" NOT give
an error ?
"someListobject" is an attribute of type java.util.List
"a" is not a property of java.util.List, so according to Servlet 2.4
specs (page I-68),
it should cause an error.
Also a question on the SCWCD exam asks this and the correct answer is
"it causes an error".
(from the book "Head First Servlets and JSP, Second Edition")

There is also nothing to be seen in the logs. (and the page is sent to
the client,
with full content, no erorrs; the EL above shows up as empty string)

Regards,
David
