Sam Adams commented on TINKERPOP-2052:
--------------------------------------

Ran across an interesting side effect while looking for a workaround:

g.V(148082784.next()  => v[148082784]

g.V(148082784).as('v').select('v').next()  => v[148082784]

g.V(148082784).as('v').id().as('vid').select('v','vid').next()  =>
{noformat}

Apparently there is a side effect is select() that selecting multiple variables impacts.

Good news is:  I have a functional workaround for the time being.  Still need a more general solution like GraphSONMapper to handle subgraphs and structures of graph elements

> Thanks [~jorgebg] for the excellent start on the GLV for javascript! Using it daily.
> Really need GraphSONMapper equivalent as my use cases need to retrieve and process graph elements and subgraphs as JSON.
> Any plans for adding this, or should I look for workarounds?
> I would imagine that we will also need this after we can submit scripts directly ala TINKERPOP-1959
