No error,
You have to call getSerial_numbers on the results of getSerialRoot() method
My getSerialRoot() method in service?
Yes, based on the initial code it will give you a SerialRoot instance, and then you can call the getSerial_numbers on that instance
and pass the resulting list to the grid setItems method
I assume you are meaning as such:
gridTest.setItems(service.getSerial().getSerial_numbers());```
That returns an empty grid
Please post the grid initialization code
I was initializing the wrong grid… <:oop:800402689941831689>
