Maybe I don't understand this quite, but there was an intention to make it possible to add feedback messages at the component level. You ought to be able to add a FormComponentFeedbackBorder to any form component even in a list view, for example. That feedback border normally would contain a little red asterisk, but if you made your own derived class, it could also show the error for that component.
http://wicket.sourceforge.net/apidocs/wicket/markup/html/form/validation/FormComponentFeedbackBorder.html The other one that might work is attaching a feedback indicator for each form component in the list. This works by filtering available feedback messages based on the component. http://wicket.sourceforge.net/apidocs/wicket/markup/html/form/validation/FormComponentFeedbackIndicator.html But feedback panels is probably not the way to do this in any case.
