public class mywebpage extends webpage {
  @SpringBean private Dao dao;

  public mywebpage() {
     add(new textfield("foo").add(new ivalidatior<string>() {
         public void validate(ivalidatable<string> v) {
            string value=v.getvalue();
            if (!dao.valueunique(value)) {
                 validatable.error(new
validationerror().addmessagekey("error.unique").setvariable("value",
value));
            }}):}

thats all there is to it
