change style class of empty fields

[dh2k7]

Hello,

I've tried to write a jsf validator, that checks if a field is empty.
If so, it should change the styleClass of the field.
Than I wanted to attach the ajaxValidator to do this in ajax.
But then I've noticed, that empty fields get not validated... :(

How can I solve this now?

Hi,

No way, that's how JSF UIInput class works:

if (isValid() && !isEmpty(newValue)) {
 if (this.validators != null) {
 for (Validator validator : this.validators) {
 try {
 validator.validate(context, this, newValue);
 }
 catch (ValidatorException ve) {
 ...

Empty values are not validated using validators.

Yes, I know.
But does anyone knows a good (and easy) way to change the style if an element if it is empty on form submit.
