I reproduced the error on other Windows 7 machine with chrome 31.0.1650.63 m. Michael, there are no javacript error in the chrome console (development tools) - so, no line numbers here. Just the two warnings I mentioned earlier. (Again, without line numbes.) And the error message at the page.

Sure; Cypher has this: http://docs.neo4j.org/chunked/stable/query-create-unique.html#_create_unique_nodes That is also backed by an index - how else would it know if there were duplicates. I don't get what you mean by involving a path. You _can_ create single, unattached nodes that are unique acc

Uniqueness only applies to indexes, so you need to tweak that url: http://docs.neo4j.org/chunked/stable/rest-api-unique-indexes.html#rest-api-get-or-create-unique-node-create On Thu, Dec 19, 2013 at 11:03 AM, Shahar Taite wrote: > I've tried this as well, > however i don't use an ad hoc REST p

I've tried this as well, however i don't use an ad hoc REST path for each node type. i just send it to http://localhost:7474/db/data/node with all of the properties. i've just tried http://localhost:7474/db/data/node?*uniqueness=get_or_create *but this still creates a new node everytime. do
