    Eventhough a4j:support is used the page is getting refreshed. Rerender is not working.
    Unless the page is refreshed the the image is not changed. Please suggest us how we can do with ajax or a4j:support without refreshing the page.

    Please advice as early as possible

  3. What i don’t realize is actually how you’re not actually a lot more smartly-appreciated
    than you might be now. You’re so intelligent. You know thus considerably relating to this subject, produced me individually consider it from so many various angles. Its like men and women don’t seem
    to be interested unless it’s one thing to do with Girl gaga! Your individual stuffs nice. At all times take care of it up!

    Thanks for the code. Saved me a lot of time. Using it with JSF2.0 (without RichFaces) and everything is working like charm. Thanks once again.

  6. Thanks, very helpful. I’ll prefer to change CaptchaAction to Validator:

    public class CaptchaValidator implements Validator {

    public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException {
    String userInput = (String) value;
    String captcha = (String) Faces.getSession().getAttribute(MyCaptcha.CAPTCHA_KEY);

    if (userInput == null || captcha == null || !userInput.equals(captcha)) {
    FacesMessage message = new FacesMessage();
    message.setDetail(“Wrong captcha”);
    message.setSummary(“Wrong captcha”);
    throw new ValidatorException(message);

    Use of Omnifaces’s Faces.getSession() can be changed to context.getExternalContext().getSession(true)

    Add this to any form (in RichFaces 5 r:ajax instead of a4j:support):
