All Implemented Interfaces:

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.

Method Detail

validateValues

public boolean validateValues(FacesContext context,
                              List<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 MethodExpression getValidateMethod()

Returns the validator method expression.

Returns:

The validator method expression.

setValidateMethod

public void setValidateMethod(MethodExpression validateMethod)

Sets the validator method expression.

Parameters:

validateMethod - The validator method expression.
