Description

When a redirect is received from the server during Ajax requests, #processAjaxResponse() explicitly calls #done() on the current call:
(wicket-ajax-jquery.js, line 777)

if (typeof(redirectUrl) !== "undefined" && redirectUrl !== null && redirectUrl !== "") {
    // In case the page isn't really redirected. For example say the redirect is to an octet-stream.
    // A file download popup will appear but the page in the browser won't change.
    this.success(context);
    this.done(context.attrs);

This leads to:

• done() being called before the step added in #success()
• done() being called a second time from the step added in #complete()
