Hi Michael,
why there's such condition testing value for None in JSONEncodeDict?
def process_bind_param(self, value, dialect):
*if value is not None:*
value = json.dumps(value)
return value
/json.dumps(None)/ returns /'null'/ which is absolutely valid JSON string.
it's a recipe. Please tailor it to your needs.

The JSON type would give you a quick way to handle the list format:
http://docs.sqlalchemy.org/en/rel_1_0/core/custom_types.html#marshal-json-strings
<http://docs.sqlalchemy.org/en/rel_1_0/core/custom_types.html#marshal-json-strings>
if you have some other string format, substitute dumps() / loads().
