That's what I'm doing, but i still get the conversion exception
public final class EmailAddressConverter implements IConverter {
private static final long serialVersionUID = -4264887925119691218L;
@Override
public Object convertToObject(final String value, final Locale locale)
{
if (StringUtils.isNotBlank(value)) {
if (Valid.emailAddress(value)) {
return new EmailAddress(value);
}
else {
throw new ConversionException("Invalid email
address.");
}
}
else {
return null;
}
}
@Override
public String convertToString(final Object value, final Locale locale)
{
return value.toString();
}
}
