You can create the DOM element using custom javascript (it's very
simple, basic DOM manipulation) invoked from
ajaxRequestTarget.prependJavascript(). Be sure that the id attribute
of new DOM element is same as new list item id.
Then just render the newly created item (target.addComponent) which
you create manually during the ajax request.
Actually, rather then using ListView for this, I suggest you using
RefreshingView, as it's more flexible.

Thanks Matej, I'm trying with RefreshingView as you recommend.
I haven't used repeaters that much, but would newItem() be the right way to
create a new Item? Anyway, I am now stuck because to ensure that the id of
the DOM element is same as the newly created item, I have to call
getMarkupId() on the item then I get the exception "This component is not
(yet) coupled to a page" Help!
