Question
After adding a boolean attribute to an object, fetching that object from the datastore results in the error:
Datastore entity with kind <Class> and key <Class:ID> has a
null property named <attribute>
Solution
Don't use primitive data-types, use their wrapper classes.
Instead of boolean, use Boolean, etc.
