Sorry, but we are not in Debug-Mode of Seam and our application exception is still eaten by seam-interceptor. In our calling method we run some hibernate-statements, which run into an NoSuchResultException, which we catches an re-throw as an ApplicationException(rollback=true). This ApplicationException is now eaten by seam, although the applicationException is not seam-annotated. See following output: 17:25:04,575 INFO [STDOUT] Hibernate: select userentity0_.ID as ID2_ from USER userentity0_ where lower(userentity0_.USER_NAME)=lower(?) 17:25:04,778 INFO [ExceptionInterceptor] no exceptions.xml file found Any Idea ?
