OK. It was working until now with components.xml in /WEB-INF, but I will follow your recommandation.
I have a new problem with this validator since it is declared as a Seam component and no more in faces-config.xml. It looks like the ValidatorException is not caught !

EqualsValidator class is annotated with @Validator and it inherits CompareValidator which has the following validate() method :
public void validate(FacesContext context, UIComponent cmp, Object value)
| throws ValidatorException {
| UIInput input = (UIInput) JSFUtils.findComponent(context.getViewRoot(), getCompareTo());
| if (! compare(value, input.getValue())) {
| String message = Messages.instance().get(getMessage());
| throw new ValidatorException(new FacesMessage(message));
| }
| }
I had a look on the way ModelValidator or FormattedTextValidator are written in Seam sources and saw no difference in the way ValidatorException is thrown. Do you have any idea about this ?
