This makes it brittle to use this for your "safety net" or "catch all" feedback panel. I had encountered this issue and for one of my training classes, I threw together a solution. Your post prodded me to go ahead and post my solution as a blog post. After dusting off my long-forgotten blog, here it is: http://www.jeremythomerson.com/blog/2011/01/catching-all-feedback-messages-that-arent-rendered-by-other-feedback-panels/(or http://bit.ly/eHUEuN if that gets chopped up). Hopefully that helps someone. -- Jeremy Thomerson http://wickettraining.com *Need a CMS for Wicket? Use Brix! http://brixcms.org*
