Captcha regeneration
Hi team;
I am trying to regenerate a captcha to help users incase the previous one
was not very clear. I have tried several things including the code below
captchaImg = new CaptchaImageResource();
captcha = new Image("captchaImg", captchaImg);
captcha.setOutputMarkupId(true);
frmRegistration.add(captcha);
frmRegistration.setOutputMarkupId(true);
IndicatingAjaxFallbackLink<String> lnkTryNewCapcha = new
IndicatingAjaxFallbackLink<String>("lnkTryNewCapcha") {
@Override
public void onClick(AjaxRequestTarget target) {
captchaImg = new CaptchaImageResource();
captcha.setOutputMarkupId(true);
captcha.render();
}
};
frmRegistration.add(lnkTryNewCapcha);
However i am not successful. Which is the best way to do this.
Regards.
Josh.

I used NonCachingImage instead and it worked.

Here is some code that I think will help
remove(image);
imagePass = randomString(6, 8);
captchaImageResource = new
CaptchaImageResource(imagePass);
image = new Image("captchaImage",
captchaImageResource);
add(image);
you can have it inside your onClick(AjaxRequestTarget target) {}
the key point to note is that you have to remove it first from the
component.
