The first problem is, that hasValue always returns true, when a value is set, even, if the value is an empty array. So the first validation for the required filter will be skipped. The second problem is, that the isRequired is called within the foreach loop. But if the value is an empty array, the loop will never start, so isRequired will never triggered and the method will return the defaultValue true.
