Subject [Jakarta-tapestry Wiki] Update of "IdeasOnTapestry" by wangzaixiang

Dear Wiki user,

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

The following page has been changed by wangzaixiang:
http://wiki.apache.org/jakarta-tapestry/IdeasOnTapestry

New page:
 Tapestry is a good framework for WEB presentation, It provide a server-side presentation
framework in a component based architecture. Tapestry3.0 is currently stable to use in a realy
web appication.

For my experience, Tapestry is still something complex for the starter to learn, but if you
would just the simple functions which is already stronger than Struts, i think 2-3days is
enough.

Also, i think the Tapestry framework should involved in the following:

   1. Simplify the component definition. Although the (POJO + XML Descriptor) model runs,
i think a purely POJO component model(without XML, or by using Java5 annotation) will be more
easily. also, It should make component develop follows the java style, such as support component
inherit. (as a compatable option, a tool can used to generate the XML descriptor. )
   2. ognl is used as internal java-bean-path language, that works well but still not enough
for big enterprise application, because ognl is not strong typed, and any error cant find
till runtime. so i would like to introduce 2 other method. one is java:a.b.c which should
be static checkable, and the error can be find on a precheck mode. or xpath:xml-path-expr
format which enable access XML using xpath.
   3. a Tapestry page is shared for multi-client and multi-request, this makes the tapestry
page 's DOM structure(or the component-tree) is static. in some cases, it makes dynamic web
appication difficult. so i think Tapstry should enable for dynamic Component tree. that require
more memory but provide a clear design.
   4. Tapestry is originaly design as Server-side presentation framework, although it provide
some javascript support but it is really poor. Rich-client is the trend of WEB, and i would
like to see a rich client based subproject to coorpate with server side framework. aka, to
integrate the AJAX into tapestry.
