is it possible to add more then one contraint (object that implement the constraint interface)to a textbox ?

is it possible somehow to check if a textbox is in error considering the a particular constraint by code on the server, for example:

Constraint constraint = textbox.getConstraint();

contraint.isInError() returns boolean ?

I see in the api for constraint that there is one method that returns a boolean:
I try to use this but it seems it's there for some other reason ?

as i understood the api there is nothing like isInError(), but you can retrieve the constraint from a component and call the validate method direct. if you want to handle the error yourself you probably have to catch the WrongValueExeception thrown by validate:

Textbox nickname = (Textbox) comp.getFellow("nickname"); Textbox email = (Textbox) comp.getFellow("email");

//throws WrongValueException
nickname.getConstraint().validate(nickname, nickname.getValue());
email.getConstraint().validate(email, email.getValue());

isClientComplete is used to denote whether all validation can be done by JavaScript codes. If true, it optimizes one round-trip communication overhead.
