Hi,
2) Work with mind bridge to see what these patches he had for OGNL were a
long time ago that theoretically sped up runtime performance of these
operations. I see that these things are already being compiled and cached
though, so I'm wondering if this effort is even needed.
I am afraid standard compilation is not sufficient. Even compiled, OGNL
uses reflection to access the data. In the optimization I used Javassist
to access the data directly with compiled code to JVM, which resulted in
the significant speedup against compiled OGNL code (9 times, as far as I
remember). This did not cover the whole OGNL, but only property access,
however.
Drew started working on OGNL 3.0 which I believe was designed to handle
such "compilation" (instead of reflection). If anyone desires to do so,
they could look at the code there and determine its potential...

If there was a theoretical person who wanted to cut their teeth on tapestry
a little more closely than just using it, what would everyone like them to
work on ?
I know we'd all like documentation / various infrastructure stuff done but
this is more an exercise in learning tapestry internals as well as proving
coding abilities and such...So, the value has to be on both sides.
I don't think there's anything we could throw at this theoretical person
that they couldn't handle, so feel free to think of whatever you like. Keep
in mind that I think we should probably just pick one for now, so think
about it before voting :)
My two ideas so far are:
1) Find a way to do what I described earlier with elimintating the need to
specify a translator binding...If this means working with Patrick Lightbody
over at opensymphony (where the ognl code now lies dormant) , then so be it.

3) Work with whoever exists in the community doing hibernate things with
tapestry and make Howard's EditObject blog entry a reality. This would
hopefully be done in some project either hosted as a sub project on
http://howardlewisship.com or as part of an existing project, like honeycomb
/ James Carmen's work with trails / hiveutils / etc...
I'm personally hoping for #3 because I think it will provide the most value
for the community. Everyone's input is welcome.
