Re: [Neo4j] update node properties via rest?
Is there a plan to fix this or will updates continue to be overwrites? Many thanks!

I don't see this as a bug.

Re: [Neo4j] update node properties via rest?
It's the basic documented update form the manual post to /properties. You can even do it in the console and it will exhibit the behaviour. I you need it I will send you my query later on ... Thanks!
