Cristian, I have finished the same lab, and in that particular task I though the same as you, and I think its another way to solve the same task, but maybe an implicit restriction is NOT TO USE ANOTHER INTERFACE, and with your solution we are using another interface, now both solutions (yours, and workbook one) work fine, but talking about the exam and its restriction only workbook one does.
cheers.
