you can use the wicket:container tag instead of span if you dont want
anything in the output.
alternatively you can call setrenderbodyonly(true) on the offending
container, if it is part of the listview/refreshingview you have to
call
onpopulateitem(Item item, ...) { item.setrenderbodyonly(true); }
