There is already such an issue filed: #33 "User defined traversal orders". > > /peter > -- > GTalk: neubauer.peter > Skype peter.neubauer > ICQ 18762544 > GTalk neubauer.peter > Phone +46704 106975 > LinkedIn http://www.linkedin.com/in/neubauer > > http://www.neo4j.org - New Energy for Data - the Graph Database. > http://www.ops4j.org - New Energy for OSS Communities - Open > Participation Software. > http://www.qi4j.org - New Energy for Java - Domain Driven Development. > _______________________________________________ > Neo mailing list > [email protected] > https://lists.neo4j.org/mailman/listinfo/user > -- Tobias Ivarsson <[EMAIL PROTECTED]> Hacker, Neo Technology www.neotechnology.com Cellphone: +46 706 534857 _______________________________________________ Neo mailing list [email protected] https://lists.neo4j.org/mailman/listinfo/user
