You add new item like this:
String id = rv.newChildId();
Item item = rv.newItem(id, index, model);
rv.populateItem(item);
rv.add(item);
(where rv is the refreshing view. Some of the methods might be
protected, so you will need to subclass the view, but you have to do
it anyway, as you need to implement populateItem);
after you call rv.add(item) you can call item.getMarkupId();
Creating DOM in javascript is simple:
var div = document.createElement(div);
refreshingViewContiner.appendChild(div);
div.id = id
One more thing Matej - last line above you meant div.setAttribute('id',
id) right? Or is there some js foo I should know about?
-Matej
Just as I was thinking Wicket was not so perfect for Ajax...
It works! Thanks Matej :) I really did need that guidance on
constructing and adding new item to RefreshingView. And of course now I
get
why ListView would not have worked.

Are you sure it's going to be a problem to update the whole

Agreed, I'm now curious to see how far I can get, and I may not

this is the same approach:

Maybe you can override getMarkupId() for your item components
to return e.g. myId + domainObject.getdId () or something
such.
(Btw, now that we're on it, all-numeric ids that repeaters
produce by default are invalid HTML. Maybe I should file a
Jira issue about that.)

[Wicket-user] Adding item to ListView over Ajax - refresh only newest row
Hi, I'm trying to create a kind of expression builder UI, so I was thinking of a ListView and there is this add button on the page that will add an item to the List. I am able to do this over Ajax, and I am aware that to refresh a ListView over Ajax, you have to target a container of the ListView and all this is working fine. But this means that in the Ajax response, the HTML for the entire list is retrieved from the server. Since the list may get big and the content is complex, is it possible to only get the last ListItem and do a DOM append operation over Ajax? Does Wicket's built in Ajax support this. Any ideas would be appreciated. Thanks, Peter. - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML. No limits.

Re: [Wicket-user] Adding item to ListView over Ajax - refresh only newest row
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. -Matej On 6/24/07, Peter Thomas [EMAIL PROTECTED] wrote: Hi, I'm trying to create a kind of expression builder UI, so I was thinking of a ListView and there is this add button on the page that will add an item to the List.
