I cannot load properly subclasses. Data is correctly stored in the datastore (mysql), however when querying data is either not found (in one method of the test case) or a field is set improperly to null.
A, A1(subclass of A)
B, B1(subclass of B), B2(subclass of B)
B has a reference to A (one (A) to many (B) relation)
After creating the schema with Schema tool, the first run of the test case goes fine. At second and successive runs however, when data is already present in the database, it does not work. Method getWithSubclasses() fails to find any result. Method getSeparately() finds the result, but field "additional" of class A1 is set to null where it should be "ZZZ"
