             Summary: Dynamic vertex by id lookups
                 Key: TINKERPOP-1090
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-1090
             Project: TinkerPop
          Issue Type: Improvement
          Components: process
    Affects Versions: 3.1.0-incubating
            Reporter: Daniel Kuppitz

gremlin> g.inject(0L).as("id").V().has(id.getAccessor(), 0L).iterate().toString()
==>[InjectStep([0])@[id], TinkerGraphStep(vertex,[~id.eq(0)])]
gremlin> g.inject(0L).as("id").V().has(id.getAccessor(), select("id")).iterate().toString()
==>[InjectStep([0])@[id], TinkerGraphStep([],vertex), TraversalFilterStep([PropertiesStep([~id],value), SelectOneStep(id)])]

==>[InjectStep([0])@[id], TinkerGraphStep(vertex,[~id.eq([SelectOneStep(id)])])]

The last compiled query is wrong, because we don't have a method overload for {{has(accessor, traversal)}}. The second one looks good and should return the same result as the first one, but its result is always empty.

==>v[0]

gremlin>
