stephen mallette commented on TINKERPOP-1860:
---------------------------------------------
Thanks for pointing this out. Upon investigation I'm seeing that we didn't have
a great body of tests for {{valueMap(true)}} - i'm adding some as part of this
fix. I notice that you are using GraphSON 3.0 which I had trouble configuring
with our tests - see TINKERPOP-1844 - i suspect the problem will get fixed as
part of that issue, so for now, I guess, this issue depends on that one. fwiw,
GraphSON 2.0 seems to work just fine with {{valueMap(true)}} the additional
tests I added in my branch of tp32/master both work.
