                              List<Object> values)

Validate if all or none is filled out.

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

Returns:

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

shouldInvalidateInput

protected boolean shouldInvalidateInput(FacesContext context,

In an invalidating case, invalidate only those inputs which have an empty value.

Overrides:

shouldInvalidateInput in class ValidateMultipleFields

Parameters:

context - The faces context to work with.

input - The input component which may need to be invalidated.

value - The value of the input component.

Returns:

Whether in in an invalidating case the given input component should be marked invalid
