Me again, sorry :) After reading other topics, I downloaded seam CVS. It works much better even if i also have "Swallowing exception thrown by page action" error. At least I'm now sure the pages.xml and rules files are taken into account. One more question : in the documentation, you added a "Requirements" section. I noted that "commons-lang-2.1.jar" is not in application.xml neither it is copied in the final ear (I started froma seam-gen project). I added it to both.
