I can imagine those two components together is asking for trouble... The easiest way to solve this is to not use feedbackpanels at all, but instead a custom mechanism (just labels that work on a shared model or even use page.getFeedbackMessages for instance). But that's kind of a lame answer from us I guess. Alternatively, you could write a simple quickstart project with what you want (or a test case might even be better) and we can take a look at if/ how/ what we can do to make Wicket handle this or what a good workaround is.
