Ok i think I found an example that is independent of my data (adapted from http://docs.neo4j.org/chunked/snapshot/gremlin-plugin.html)
Locally: gremlin> m = [:];g.v(33).bothE().label.groupCount(m) >> -1;m ==>follows=11 ==>owns=48 gremlin> m = [:];g.v(33).bothE().label.groupCount(m) { it }{ it += 0.1 } >> -1;m ==>follows=1.1 ==>owns=4.8 REST/webadmin console: gremlin> m = [:];g.v(33).bothE().label.groupCount(m) { it }{ it += 0.1 } >> -1;m ==> follows=11 ==> owns=48 gremlin> m = [:];g.v(33).bothE().label.groupCount(m) { it }{ it += 10 } >> -1;m ==> follows=11 ==> owns=48 gremlin> It seems like the closure block is not evaluated (to me as a Groovy/Gremlin/Neo4j noob) Michael, I will send you a link to my database in private.
