invoking an ajax refresh

[Daniel Dominik Holúbek <da...@gmail.com>]

hello everybody,i am wondering how to invoke refresh of a component with
ajax.
the situation:
i have a listener listening for incoming messages. if a message is fetched,
a method is executed, and I add the message text into a List object.
I then want to refresh the ListView (or the parent WebMarkupContainer), so
that it shows the latest message up.

So basically, it's a sort of asynchronous chat.
Thanks! :)

maybe

new AjaxSelfUpdatingTimerBehavior( Duration.seconds(2) ){
  private static final long serialVersionUID = 1L;

  protected void onPostProcessTarget(AjaxRequestTarget target){
    // Add new feed back message
    target.addComponent( .... );
}
};

Hi Daniel,

Please investigate AjaxSelfUpdatingTimerBehavior. I have never used it 
myself so I can not help you further then that.

Regards,
    Erik.
