A work around is to roll your own Exceptions component e.g. @Scope( ScopeType.APPLICATION ) @BypassInterceptors @Install( precedence = Install.MOCK, classDependencies = "javax.faces.context.FacesContext" ) @Name( "org.jboss.seam.exception.exceptions" ) public class Exceptions extends org.jboss.seam.exception.Exceptions { @Override public void handle( Exception e ) throws Exception { throw new AssertionError(e); } } but this is something I should not have to do. see http://jira.jboss.org/jira/browse/JBSEAM-2138
