Hi
The only book on T4 is Kent Tong's Enjoying Web Development with
Tapestry (http://www.agileskills2.org/EWDT/), but even tough it has a
good depth in T4 concepts, it's exactly what you don't like: a classic
step-by-step example book. It even has screenshots of every single
configuration window in eclipse.
Beginning POJOs also covers T4, but only superficially.
I think the best option is the T4 documentation on the Tapestry site
and then some hacking in its source code.
Saludos.
Alejandro.
