Faces UI field validation

To validate an individual UI field from Faces Side(Mostly for POJO Trees) and dis-allow user to submit the form with Save button, 2 things you need to do
In JSFF, for the UI component, add a Validator Method as below

                <af:inputText value="#{node.Email}" id="i21"

In ManagedBean, add the logic like this

    public void ValidatorEmail(FacesContext facesContext,
UIComponent uIComponent, Object object) {
FacesContext fc = FacesContext.getCurrentInstance();
String email = (String)object;
if (email != null && !email.contains("@")) {
FacesMessage message = new FacesMessage(FacesMessage.SEVERITY_ERROR, "The Email Id must contain @","The Email Id must contain @");

This wont allow to submit the form unless user rectifies the validation error, because the UIComponent's state is invalid.
