And, I have... .
Take the wicket 1.2.2 quickstart application and unzip the archive
into that directory. The main page (Index) contains a feedback panel,
a link to the Other page and an info message showing a counter. The
counter is incremented every time the Index page is rendered and
info() is used to display the counter on the page.
Now, try this:
* start the application: -> Info message is shown with counter is 0
* click on the link, now click on 'Return to previous page'-> No info
message is hown
* refresh the page by clicking the browser's refresh button -> info
message is shown with counter is 2
This shows that the info message which is generated in the onAttach()
method somehow disappears. It is only rendered when the page is
refreshed but not when you return to the page by an explicit
setResponsePage() call.

Since sourceforge does not allow zip extensions in a fruitless attempt
to protect Microsoft windows users, here are the files: Index.java,
Index.html, Other.java, and Other.html.

add(new Link("link") {
@Override
public void onClick() {
setResponsePage(aReturnPage);
}
});
}
}
