Bruno, your problem is more of an issue with code beauty and design? I
agree that it's a bit misleading to have an setVisible method that
does nothing... As adding a fairly synthetic AjaxComponent subclass to
Component for using as a parent for every ajax-enabled component
doesn't seem justified, what if ListView (and other possible
repeaters) would throw UnsupportedOperationException or something like
that?
Of course, that would mean making Component.setVisible not final...

i disagree,
wicket's primary usecase is not ajax, but regular rendering. ajax is a very
nice bonus and does not always work as smoothly as we would like.
now the ajax solution for the listview is quiet easy, put it into a
webmarkupcontainer and update that container instead of the listview via
ajax
WebMarkupContainer listviewcontainer=new
WebMarkupContainer("listviewcontainer");
ListView listview=new ListView("listview", .....
listviewContainer.add(listview);
<span wicket:id="listviewcontainer"><ul><li
wicket:id="listview">blah</li></ul></span>
... target.addComponent(listviewcontainer);
this has the added advantage of hiding the listview's container, be that a
ul or a table

Label or TextField, it works, right? So, for ListView it should work too.
It's a component just like other.
