Juergen Zimmermann commented on AS7-1348:
-----------------------------------------

Thank you! Your workaround works. So what's the conclusion? Is it a regression? I would say: yes. But of which component? Perhaps in RichFaces they could take care of it, when they implement tags like <rich:graphValidator ... groups="my.package.MyGroup">. Should I open an issue in their project?
