*crickets*
Anyway, I finally found the likely answer in the form of an extended
PageRequestTarget.
However, it seems the call to urlFor() returns a link that does not
invoke the code as expected; it just re-renders the same page and panel
instead of invoking my object. Am I doing something wrong regarding the
urlFor call? Does the request target object need to be registered
somewhere?
// ...
CharSequence urlFor = RequestCycle.get().urlFor(new
ChangeArticleRequestTarget(getPage(), token.getLinkData()));
public static class ChangeArticleRequestTarget extends
PageRequestTarget {
private String articleId;
public ChangeArticleRequestTarget(Page page, String
articleId) {
super(page);
this.articleId = articleId;
}
@Override
public void respond(RequestCycle requestCycle) {
Page page = getPage();
BreadCrumbBar bar = (BreadCrumbBar)
page.get("breadCrumbBar");
try {
ArticlePanel newPanel = new
ArticlePanel("articlePanel", bar, new
Model<Integer>(Integer.valueOf(articleId)));
page.replace(newPanel);
bar.setActive(newPanel);
page.dirty();
}
catch (NumberFormatException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
super.respond(requestCycle);
}
}
