Hi, If the Neo4 graph is created first with Blueprints (not pre-existing), then the root vertex is removed as that is not a concept support by Blueprints. Its not a bug, its a feature :).
NOTE: If you create Neo4j graph with Neo4j and then load up a Neo4jGraph around it, then Blueprints will not alter the structure (i.e. remove the root vertex). See ya, Marko. http://markorodriguez.com On Jun 9, 2011, at 5:32 AM, Pierre De Wilde wrote: > Hi Peter, > > You're right: when reopening in gremlin, same recovery message. > I will report this issue + node 0 to gremlin mailing list. > > Thanks, > Pierre > > > 2011/6/9 Peter Neubauer <peter.neuba...@neotechnology.com> > >> Pierre, >> it seems that the db is not closed properly, it tries to resolve >> transaction upon startup.
