stephen mallette updated TINKERPOP-1391:
----------------------------------------
Assignee: Daniel Kuppitz
Affects Version/s: 3.1.3
Fix Version/s: 3.1.4
Component/s: process
[~arikc] note that the workaround for now would be to write your traversal as:
{code}
gremlin> g.V().hasLabel('GROUP').where(__.outE("PART_OF").count().is(0))
==>v[0]
{code}
Looks like a bug in the traversal strategies:
{code}
gremlin>
g.V().hasLabel('GROUP').where(__.outE().hasLabel("PART_OF").count().is(eq(0))).explain()

{code}
{{NotStep}} shoudl be wrapped around {{VertexStep}} and {{HasStep}}. It should
generate this:
{code}
gremlin> g.V().hasLabel('GROUP').where(__.outE().not(hasLabel("PART_OF"))) //
what it does
gremlin> g.V().hasLabel('GROUP').where(__.not(outE().hasLabel("PART_OF"))) //
what it should do
==>v[0]
{code}
