partial ajax updates on repeater components
-------------------------------------------
Key: WICKET-1177
URL: https://issues.apache.org/jira/browse/WICKET-1177
Project: Wicket
Issue Type: Improvement
Components: wicket
Reporter: Peter Ertl
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).
