> When validation performed on input of type h:selectManyCheckbox (bound to property of type List<String>) on backing bean), and unexpected error appear. See details for Mojarra and MyFaces in log attached.
> Since property bound to property is List type, SizeValidatorForCollection validator implementation is called. But submited items from h:selectManyCheckbox are sent to appropriate method (isValid() ) as String[]. (Every item from selectManyCheckbox is another array item). Its the same behavior for Mojarra and MyFaces.
> @Size annotation declare that it should work with String, Collection, Map and Array.
