Package org.omnifaces.component.validator

Class ValidateMultiple

  • All Implemented Interfaces:
    PartialStateHolder, StateHolder, TransientStateHolder, ComponentSystemEventListener, FacesListener, SystemEventListenerHolder, EventListener, MultiFieldValidator
    public class ValidateMultiple
extends ValidateMultipleFields

    The <o:validateMultiple> allows the developer to validate multiple fields by either a custom validator method: 

     <o:validateMultiple id="myId" components="foo bar baz" validator="#{bean.someMethod}" />
 <h:message for="myId" />
 <h:inputText id="foo" />
 <h:inputText id="bar" />
 <h:inputText id="baz" />

    whereby the method has the following signature (method name is free to your choice): 

     public boolean someMethod(FacesContext context, List<UIInput> components, List<Object> values) {
     // ...
 }

    Or, by a managed bean instance which implements the MultiFieldValidator interface: 

     <o:validateMultiple id="myId" components="foo bar baz" validator="#{validateValuesBean}" />
 <h:message for="myId" />
 <h:inputText id="foo" />
 <h:inputText id="bar" />
 <h:inputText id="baz" />
 
     @ManagedBean
 @RequestScoped
 public class ValidateValuesBean implements MultiFieldValidator {
     @Override
     public boolean validateValues(FacesContext context, List<UIInput> components, List<Object> values) {
         // ...
     }
 }

    Design notice

    Note that this validator does not throw ValidatorException, but returns a boolean! Message handling and invalidation job is up to the ValidateMultipleFields implementation who will call this method. You can customize the message by the message attribute of the tag. Refer ValidateMultipleFields documentation for general usage instructions.
