Hello, there is a book on Amazon "*Pro Ajax and Java Frameworks" * http://www.amazon.com/Pro-Ajax-Java-Frameworks/dp/1590596773/ref=pd_bbs_sr_2/102-7742188-1702530?ie=UTF8&s=books&qid=1191400626&sr=8-2
which could be in the books section at as it covers ajax and T4 http://tapestry.apache.org/articles.html It would be interesting to see an updated version covering the one year enhancements in all frameworks. Cheers, Borut
