Thank you Matej and Igor. I learned several new things. IAjaxCallDecorator
is very cool and I did not realize <wicket:link> works on stylesheet ref,
too. The wiki here:
http://cwiki.apache.org/WICKET/wickets-xhtml-tags.html#Wicket%2527sXHTMLtags-WicketTags
make it seem like it only work with <a href> and <img src>.

Do you mean this:
WebMarkupContainer img = new WebMarkupContainer("thumbnail") {
private static final long serialVersionUID = 1L;
@Override protected void onComponentTag(final ComponentTag tag){
super.onComponentTag(tag);
tag.put("src", thumbnailUrl);
}
};
== I have a couple of questions: ==
In Ajax mode, the browser address always show:
http://localhost:8080
so if I refresh, I get a new page, not the same existing page. How can I
have the address like this:
http://localhost:8080/?wicket:interface=:0:1:::
so on refresh I get the same page (like in non-Ajax mode)?
2) When something goes wrong in Flickr, I throw a RuntimeException which
blows up in ListView's model.getObject(). I want to Ajax update the
feedbackPanel to show some error message. How can this be done?
Thank you very much.
