there really isnt that much we can do, that is the lifecycle of feedback
messages, and it has to be like that because of components exactly like the
listview - the ones that change hierarchy in onattach.
so if you can describe what you are trying to do and not how maybe we can
help

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.
