Changing Value because of Validator/Converter

Question

Hello,
I'm searching for a quite simple solution for following problem:
I have a textfield with a converter:
<h:inputText size="10" maxlength="10" value="#{organizer.birthday}" >
    <f:convertDateTime pattern="dd.mm.yyyy" />
</h:inputText>and on the same page, I have an image:
<h:graphicImage url="images/img.gif" />further, I have another textfield, only for output:
<h:outputText value="blah blah blah"/>I want the url of the graphicImage and the value of the 2nd textfield to change, when an validation-error has occured. How can I manage this?
hoping for help
lg,

I'm trying to do that with an custom validator... here I got another problem....
Snippet from the ValidatorTag-Class:
         // getter and settter -Methods
     public StringValidatorTag() {
          super();
          super.setValidatorId("validator.StringValidator");          
     protected Validator createValidator() throws JspException {
          StringValidator validator = (StringValidator)super.createValidator();
          validator.setErrorImageComponentId(errorImageComponentId);
          validator.setErrorImageUrl(errorImageUrl);
          validator.setFieldName(fieldName);
          validator.setLength(length);
          validator.setRequired(required);
          return validator;
     }Snippet from the Validator-Class:
        // getter and settter -Methods
     public StringValidator() {
          super();
     public void validate(FacesContext context, UIComponent component, Object value)
          throws ValidatorException {
          if (context == null || component == null) throw new NullPointerException();
          context.addMessage("test",
                    new FacesMessage("Sie haben beim Feld '"+fieldName+"' keinen Wert eingetragen!"));
                /* here I want to change the url from the image-component
                 * but there is another problem first to solve
                 * (fieldName is empty) */
        }I made the entries in the faces-config.xml and into an tld for this tag, but it seems to be, that the values specified in the tag aren't assigned to the Validator....
I'm using ri-1.0
