inputText : Validator

[MaheshS Kumbhar]

In <h:inputText id='"UserNo" validator=""#{UserNumber.validate}/>
Here for validator attribute which is method binding expression, the method should have non-void return type as per the Spec.
Then how do we get to know the result of validation from such method that doesn't return anything?

Look at the tag docs again for the validate attribute:

javax.el.MethodExpression
(signature must match void validate(javax.faces.context.FacesContext, javax.faces.component.UIComponent, java.lang.Object)) 

Validators don't return things. They either exit normally or they throw ValidationExceptions.
