Martin Grigorov resolved WICKET-4288.
-------------------------------------
Resolution: Incomplete
>From the ticket description is not exactly clear what is the problem.
CaptchaImageResource keeps the image bytes in a transient field (imageData). If
the page is loaded from the http session then these bytes are reused.
If you want a freshly new image then use
org.apache.wicket.extensions.markup.html.captcha.CaptchaImageResource#invalidate()
in CaptchaForm#onError()
> Captcha doesn't work
