You have to call getSerial_numbers on the results of getSerialRoot() method

23

My getSerialRoot() method in service?

24

Yes, based on the initial code it will give you a SerialRoot instance, and then you can call the getSerial_numbers on that instance

25

and pass the resulting list to the grid setItems method

26

I assume you are meaning as such:

gridTest.setItems(service.getSerial().getSerial_numbers());```
27

That returns an empty grid
