ok now I see the automatic part :)
its in json.py
so instead of worrying about decoding it, we have to encode it right.
treeJSON = '[{"__jsonclass__": "Candidate.Candidate", "name": "Barack
Obama"}]' is read as a string so json.py doesn't see an object.
treeJSON = {"__jsonclass__": "Candidate.Candidate", "name": "Barack Obama"}
?
still running into errors.. will keep pressing through
