why can not create a Vertex with property key 'hasLocation'

[rever67697]

gremlin> g.V(89211000).property("hasLocation",'55156736')
The type of given name is not a key: hasLocation

gremlin> g.V(89211000).elementMap()
==>{id=89211000,  _hasLocation=55156736, has_Location=55156736, has_location=55156736, haslocation=55156736}

but above key name can success

My best guess is hasLocation was defined as a label earlier. Can you run mgmt.printSchema() and paste the results here?

hasLocation has indeed been used as a label, however, Edge naming doesn't seem to affect attribute addition

Your above example uses Tinkergraph, which has a much looser constraint on the schema than JanusGraph does. JanusGraph does not allow you to use the same name for label and property.

wow! it really does
