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) {
// ...
}
}
