Its a good idea but I;ve already been there as this is what started my problem. I was running in Development mode and JSF was adding a <h:messages > component when I didn't expect one.
Any other suggestions welcome as I'm a bit stuck on this. It's not impacting the application, but it is annoying to have errant log messages lying around.
