EL 2 Ref/Tut
Hi List,
Does anyone know of a nice Intro/Ref/Tutorial to EL v2?
(with stuff like: what is new, what implicit objects can be used, like
"request" and its instance vars like request.requestURI etc)

I'm starting to fall in love with ELv2! :-)
Thx Bruno,

Bruno/List,
On a PageNotFound page, showing
Error message: The requested File is not Found: #{request.requestURI}
... has little use (just found out the obvious) as obviously THIS
request is not the one for the page he couldn't find... :-)
-> Is there a way in EL2 to do stuff like in javascript with the
"history -1" etc?
As in fact what I want to show on that page, is smth like (ficticious)
Error message: The requested File is not Found: #{request.previousRequestURI}

You can use implicit objects such as "request", "session" and "header"
with Facelets too, so #{request.requestURI} should be perfectly valid,
but of course, you can always go through facesContext which brings a
world of possibilities :-)

Like whether #{request.requestURI} will do, or whether I would have to do:
e.g. #{facesContext.externalContext.session.request.requestURI}

If you are in a JSP view handler, JSP implicit variable are accessible.
However if you are not in JSP context (eg using Facelets as view
handler) am not sure session, request, headers, etc are available.

David,
In the doc I found that you could get to the session via
#{facesContext.externalContext.session}
Are session & request accessible *directly* as well?
To do simple stuff like e.g. #{request.requestURI} (would this work?)
