I have a type (SmartBulb) that extends another type (LightBulb). bulbMeasurement is a collection field defined on SmartBulb.
I am now trying to traverse my data model and am ending at a LightBulb but I really need to get to bulbMeasurement.
All my LightBulbs are SmartBulbs and vice versa.
Is there some way to type cast LightBulb as SmartBulb in my expression?
