Hi,
I am simply displaying a captcha image which is suppose to refresh on
hitting a button:
* final String captchaValue = generateRandomString(30);
final NonCachingImage image = new NonCachingImage("image",
new CaptchaImageResource(captchaValue));
image.setOutputMarkupId(true);
AjaxFallbackButton ajaxRegisterSubmitButton = new
AjaxFallbackButton(
"register", registerForm) {
protected void onSubmit(AjaxRequestTarget target, final
Form<?> form) {
// some processing
if (target != null) {
image.setImageResource(new
CaptchaImageResource(generateRandomString(30)));
target.add(feedbackPanel);
target.add(image);
}
}
*
The code is simple...do I need to put CaptchaImageResource, image variables
as private class variabes?
