FencedFeedbackPanel doesn't work correctly if inner form(s) are in RefreshingView(or it's implementations)..
in this case outerform feedbackpanel just starts including messages meant for inner feedbackpanel.
with ListView FencedFeedbackPanel works correctly..
actually one user(Mike Dundee) created this issue in quickview https://github.com/vineetsemwal/quickview/issues/19
so in that link he has described his problem and pasted the code you can use to reproduce ...
there i have also explained why it's broken with RefreshingView and it's implementations currently(it's a little complex so i am trying to avoid explaining all again ,also english is not my first language )
thank you !
