Summary: NPE with OLTP nested group() in an OLAP group() traversal Key: TINKERPOP-1307 URL: https://issues.apache.org/jira/browse/TINKERPOP-1307 Project: TinkerPop Issue Type: Bug Components: process Affects Versions: 3.2.0-incubating Reporter: Marko A. Rodriguez {code} graph = TinkerGraph.open() graph.io(graphml()).readGraph('data/grateful-dead.xml') g = graph.traversal().withComputer() g.V().hasLabel('song').match( __.as('songV').values('name').as('songName'), __.as('songV').out('followedBy').as('followedV'), __.as('followedV').values('name').as('followedName'), __.as('followedV').out('sungBy').as('sungByV'), __.as('sungByV').values('name').as('sungBy'), __.as('followedV').out('writtenBy').as('writtenByV'), __.as('writtenByV').values('name').as('writtenBy') ).select('songName','followedName','sungBy','writtenBy'). group().by(select('songName')).by(group().by(select('followedName')).by(select('sungBy').fold())) {code} The above causes an NPE. I know why -- potentially easy fix. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
