I read Michael Yuan + Thomas Heute's Seam book, it's pretty good but information in that book needs to be updated since Seam is under drastic change. Most of the time, I find Seam reference manual pretty sufficient. I open the reference in a single html and global search is then much easier. If the reference doc does not answer all my questions or my usage of some Seam features turned very exotic, I resorted to this forum and always got informative replies. (If only the search function of the forum could be more usable) Sometimes, if you are stuck by some really strange behaviours of the framework and want to know what's happening under the hood, source code of Seam is the best answer. That's why some people do Seam cvs update everyday to fetch the latest source code, even thought they are not official Seam developers. If Seam source code alone does not help, you might want the source code of some 3rd party libs, for example, hibernate, javassist,....even the source code of jdk. If the source code of jdk still does not help you find the root of your problem, you might want to look at the "native code" of your OS.
