> In the console we get this:
> {code}
> gremlin> v2 = g.V(2).next()
> ==>v[2]
> gremlin> g.V(1).out().inject(v2).values("name")
> ==>vadas
> ==>lop
> ==>vadas
> ==>josh
> {code}
> From gremlin-python we can see:
> {code}
> >>> v2 = g.V(2).next()
> >>> g.V(1).out().inject(v2).values("name").toList()
> [u'lop', u'vadas', u'josh']
> {code}
> and using {code}withRemote(){code} in java:
> {code}
> gremlin> v2 = g.V(2).next()
> ==>v[2]
> gremlin> g.V(1).out().inject(v2).values("name")
> ==>lop
> ==>vadas
> ==>josh
> {code}
> Since {{inject()}} doesn't re-attach the vertex when {{values()}} gets called it acts on a reference vertex with no properties and returns nothing.
