All Implemented Interfaces:

EventListener, javax.faces.component.PartialStateHolder, javax.faces.component.StateHolder, javax.faces.event.ComponentSystemEventListener, javax.faces.event.FacesListener, javax.faces.event.SystemEventListenerHolder, MultiFieldValidator

public class ValidateMultiple
extends ValidateMultipleFields

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) {
         // ...
     }
 }

Method Detail

validateValues

public boolean validateValues(javax.faces.context.FacesContext context,
                     List<javax.faces.component.UIInput> components,
                     List<Object> values)

Invoke the validator and return its outcome.

Parameters:

context - The faces context to work with.

components - The input components whose values are to be validated.

values - The values of the input components to be validated.

Returns:

true if validation is successful, otherwise false (and thus show the message).

getValidator

public MultiFieldValidator getValidator()

Returns the validator instance.

Returns:

The validator instance.

setValidator

public void setValidator(MultiFieldValidator validator)

Sets the validator instance.

Parameters:

validator - The validator instance.

getValidateMethod

public javax.el.MethodExpression getValidateMethod()

Returns the validator method expression.

Returns:

The validator method expression.

setValidateMethod

public void setValidateMethod(javax.el.MethodExpression validateMethod)

Sets the validator method expression.

Parameters:

validateMethod - The validator method expression.
