<p dir="auto">this issue is unfortunately not in with neo4j itself, but a problem with how javascript handles long numbers... It does however make the web based management tools hard to use as you cannot use the values you are seeing. We encountered a similar issue on the front end of our application, and overcame by serializing our Id's as strings on our client view models (not ideal, but we're using a lot of javascript in our front end)<br>
