Is this possible?
We have a page that has a rather big DataView list. We need to be able to
make insertions and removals of this list without sending back the whole
list via AJAX as its a bit slow over the wire.
Is it possible to add a new element and return and insert that into the
list? Obviously we could insert in new item with JS on the page but we
still want to take advantage to any handlers in wicket for that new item
inserted into the list.
So something like:
....onSubmit(AjaxRequestTarget target)
{
Item<MyModel> item = new Item(); //!!
item.add(new AjaxFormComponentUpdatingBehavior("onchange")
{ protected void onUpdate(AjaxRequestTarget target) {...}});
thelist.add(item); //!!
...
target.appendJavaScript(js);
}
thanks
Wayne

You can try wicket-quickview, which is based on the stuff in the link
Martin provided. It works pretty well IMHO, and it is Wicket 6.0 compliant:

Hi,
I'd recommend you to use JS for something like this.
See
http://wicketinaction.com/2008/10/repainting-only-newly-created-repeater-items-via-ajax/
.
Additionally I'd recommend to use event delegation, i.e. one change
listener on the dataview that handles 'change' for all items.
