I think the issue might be a previous set() function defined in the interface returns the interface class type, and then a new set function is called on the interface. This can be checked by separating the calls to set...() functions into separate calls on the numbered on the numbered object, so they are not chained together. This can be tested by hand modifying HelloWorld.py and removing the chaining and putting each set() call in a separate statement. I will try to modify my serializer to do this when I get the chance.
