Hello, I have not found an errata page for this grandious well written book yet. http://www.michaelyuan.com/blog/seam-next-gen-web-framework/ Does one exist? In particular Chapter 11.1.3 Use Extended EL in Data Table was discussed more than once in this forum. I can't remember the correct thread but Christian Bauer has stated that extended EL can not be used as described in the mentioned chapter. So an errata page is very usefull. BTW: I do not have an safari account. What state has the book in the safari area. Are these tiny little qirks already corrected there?
