Subject [Tapestry Wiki] Update of "BoardReportApril2007" by JesseKuhnert

Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Tapestry Wiki" for change notification.

The following page has been changed by JesseKuhnert:
http://wiki.apache.org/tapestry/BoardReportApril2007

New page:
== Tapestry 4.1.2 ==
Development of the 4.1.X series continues with what are more or less largely feature improvements
/ bug fixes / elimination of "quirks". This release is currently only waiting for the new
OGNL features to stabilize - which we hope happens soon. (maybe 2-3 more weeks if you are
feeling optimistic)

=== OGNL 2.7 ===
One of the feature improvements involved improving the runtime performance of a critical library
used to resolve java object property expressions. 

Most of the details can be found in either links [http://blog.opencomponentry.com/2007/03/05/tentative-ognl-27-snapshot-release-out-to-blow-up-a-project-near-you/
OGNL 2.7-SNAPSHOT released], [http://blog.opencomponentry.com/2007/01/14/new-ognl-release-on-the-horizon-its-faster/
new ognl release coming..]. The gist of it is that a new bytecode compilation step has been
added to the process to translate the ast generated object graph from typical ognl expressions
into their pure(er) java bytecode form - making for a much faster runtime. 

It is expected that these changes will also eventually make their way into [http://struts.apache.org/2.0.6/
Struts 2]. Specifically - Patrick Lightbody from opensymphony / Jesse have been collaborating
on bringing the project forward and outlining features that more projects need with newer
jvm's. (such as [http://opensymphony.com/xwork XWork] / webwork / struts2 / etc...) There
is even speculation that should the 1.5 java.lang.Type support come in Tapestry 5 may think
about using them.
