Description

I try to explain the problem using an example:

Imagine having a guestbook page where you can add new user entries via ajax post...

Assume we are using RefreshingView to display the user entries. Once a user submits a new post the view should not be re-rendered in the ajax response completely but only the new user entry.

Technically it's easy to address the view items by using e.g. ListItem#setOutputMarkupId(true).

However, things are more complicated.

When the user clicks on the submit button a background ajax request is created and a form submit listener is invoked. There the new guestbook post is saved in the data model. Then you want to update the list with the new entry using target.addComponent(..) . Also, applying a yellow fade effect to the component would be cool as an visual indication for the user. However, there is no way I can think of to get the proper view item(s) for the model object (=new user entry).
