JSF 2.2 Early Draft Review Available

Three days ago, the JSF 2.2 Early Draft Review Specification was
released. You can download it from
and the in-progress reference implementation can be obtained by
following the instructions
in my
blog entry from 26 September 2011
. With this blog entry, I want to
quickly survey the new and proposed features, not all of which are
implemented in Mojarra yet. The following content is taken from the
Preface section in the PDF document, which is and always has been your
one-stop-shop for discovering what's new in the spec.

Let me begin by re-stating what I've been saying since the JSF 2.2
kickoff BOF at CON_FESS Vienna
last year: 2.0 was the last BIG FEATURE release of JSF. From now on,
JSF will be maintained with smaller, more frequent releases. I'm hoping
to get JSF 2.2 done in the first half of 2012. The first thing you'll
note about the "Changes between 2.1 and 2.2" section: it's just a list
of JIRA issue with a description of each one. You can read through the
list just as well as I can so I'll just call out the more interesting
ones here.

Mostly Specified Features


This one is taken directly from Seam's Faces Module. This feature
viewMetadata to the next level by letting you include actions in the
metadata and customizing how and when the action is delivered. Just a
is an EditableValueHolder,
is an ActionSource2.


Make it possible for a Facelets Tag Library to have both composite
and non-composite components.


Every kind of artifact created by JSF is now fully injectable via CDI
and also can have @PostConstruct
and @PreDestroy annotated methods which will get called at
the right time.


Standardize how JSF provides CSRF protection.


Make it possible to declare a Facelets ResourceResolver
without using XML.

Not Yet Fully Specified Features


Bring the best of Spring Web Flow, ADF Task Flows, and MyFaces CODI
to the JSF spec. This feature intends to provide support for
encapsulating related views together such that applications can be
created as composites of modules of functionality, with each module
consiting of well defined entry and exit conditions.


Finally add a component for file upload.


My friend and fellow
blogger Mamadou
Lamine Ba
has done some great work on this idea and is donating the
core of it to the JSF 2.2 spec. The idea is to bring the best of
Joomla! to the JSF spec. When you combine this feature with
730-TaskFlows, and put the result on top of the cloud features of JavaEE
7, you have a very compelling multi-tenant capable platform. Please see
Lamine's blog entrys
from 28
August 2011

and 5
June 2011
for some great details and a sharp looking demo, running
on Google App Engine.

Am mostly excited about:

  • CSRF protection: it would be nice if this feature goes into Servlets spec instead.
  • TaskFlows.
  • MultiTemplating: It would be nice if you can add placeholders declaration to templates where a component contribute markup let say I have this snipest in a facelets template <div role="placeholder" name="header-area"></div> a {composite}component loaded from a jar droped into classpath (or a configurable dir specified by a context attribute) would express intent to contribute markup/style to a placeholder with name "header-area".

TaskFlows !!! That's brilliant. It really was the missing bit of the puzzle in EE. You have fulfilled a dream of mine ;o)

I appreciate your enthusiasm, but the dream is not yet fulfilled!  I'll work that much harder on it because of your kind post, though.

I think that all the features will be fantastic additions to JSF but my favorites would be TaskFlows and ViewActions.
