Tom Brown updated TINKERPOP-2331:
---------------------------------
Description:
It looks like dotnet version does not support selecting multiple vertices by
aliases and following syntax always throws an exception
Select("key1", "key2").By(__.ValueMap(true))
System.InvalidCastException: 'Unable to cast object of type
'System.Collections.Generic.Dictionary`2[System.Object,System.Object]' to type
'Gremlin.Net.Structure.Vertex'.'
*Steps to reproduce:*
_1. Create following test graph_
graph = TinkerGraph.open();
g = graph.traversal();
g.addV().property("name", "B").
addV().property("name", "A");
_2. Query from Gremlin console to verify that query syntax is OK_
g.V().has("name", "A").as("a").out().has("name", "B").as("b").select("a",
"b").by(valueMap(true))
_3. Query from .net to get an exception_
g.V().Has("name", "A").As("a").Out().Has("name", "B").as("b").Select("a",
"b").By(__.ValueMap<object, object>(true)).ToList()
