Hi
As Alan mentions, this is a side-effect of both Neo4j's type system and the
JSON format used by the HTTP server. The type system at store level has no
concept of an untyped array and JSON has no way to transmit type
information independent of value, so it's impossible for the server to
determine what type the received array should be stored as. Clark's
suggestion of using a null would be typically used here; your application
can then choose to interpret a null/missing property as an empty list.
