--------------------------------------
Summary: Neo4j GraphStep with element arguments ignores has
Key: TINKERPOP3-822
URL: https://issues.apache.org/jira/browse/TINKERPOP3-822
Project: TinkerPop 3
Issue Type: Bug
Components: neo4j
Affects Versions: 3.0.0-incubating
Reporter: Geoff Reedy
When a neo4j traversal is started with explicit elements these elements are
returned even if they do not satisfy has filters that have been merged into the
start step. For example:
{noformat}
gremlin> graph = Neo4jGraph.open('/tmp/neo4j')
==>neo4jgraph[EmbeddedGraphDatabase [/tmp/neo4j]]
gremlin> v0 = graph.addVertex(label, "foo")
==>v[0]
gremlin> g = graph.traversal()
==>graphtraversalsource[neo4jgraph[EmbeddedGraphDatabase [/tmp/neo4j]],
standard]
gremlin> g.V(v0).has(label, "bar")
==>v[0]
gremlin> g.V(v0).map{it.get()}.has(label, "bar") // map prevents has from
merging into start step
gremlin> g.V(v0).has("a", "b")
==>v[0]
{noformat}
