Java Server Faces is currently full of relatively undocumented features and behavior. As part of the JSF2 release, OcpSoft is working with a few folks at Seam/Redhat to try to address these issues and provide better documentation. Do you know something about JSF that people should be aware of? Go to the site: http://ocpsoft.com/java/undocumented-jsf/ Add a comment with your experience or “gotcha!”
