Great stuff Howard,
Get the public API right and you can decouple the framework from
applications enough to make user upgrades straightforward even for quite
significant internal changes.

I hope you're planning to design the API in a "clean room" to be the best
fit users' requirements then change the framework to fit the API.
One of the most attractive features of Tapestry is component reuse, but
this can sometimes be undermined (a bit, not a lot) by tight coupling with
the framework, and by the fact that Tapestry constrains the way in which we
can use inheritance and polymorphism in the bits we (users) write. Many of
the most useful examples of java technologies are based around wholly
abstract API's, with some boilerplate thrown in, IMHO it would be a big
step forward for Tapestry to adopt this pattern too.

Are you going to post your initial ideas about the basic entities, event
model and component interfaces for us to give you feedback on?
