Johan, I tried to recreate the problem that the properties file can't be found. I made a war that contains only the ExtVal libs and the JSF jars (with commons logging and JSTL) were placed in the lib directory of tomcat. I used you config options (about locale config) in the webfaces-config file.
Tested only standalone (outside the IDE) but couldn't find any issue. At least for the @length annotation, there was no problem. So at this time I can't help you any further with that. Sorry regards Rudy.
