public class ValidateMultiple
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) { // ... } }
