Ideas on tapestry

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.
