Olá!
rich:messages isn't showing the "passedLabel" when a form is submited correctly. You can notice that in the RichFaces Examples Site... If you look at it's example code, the message "Data is allowed to be stored." should appear when all validations are ok, but it doesn't.
yes this functionality was eliminated a long ago, because of conflicts with seam ligecycle. Will be removed from demosite.
