Byron Bailey updated TINKERPOP-2228:
------------------------------------
Description:
When using the by(valueMap(true)) step when using the gremlin javascript
plugin, a result set is returned but the properties are all missing. The same
query works from the console. Additionally, the same query without
by(valueMap(true)) returns a valid result set.
Below is the sample code with the output, along with the same query against the
same graph using the console. The test case is a simple server architecture
with a "host" node having three edges connecting it to 2 "vm" nodes and a
chassis node. I have also tried the identical query using client.submit() and
receive failed results.
{code:java}
const g = traversal().withRemote(new
DriverRemoteConnection('ws://localhost:8182/gremlin'));{{}}
const __ = gremlin.process.statics;
function getNeighbors(label, uuid){
console.log("> getNeighbors "+label+"["+uuid+"]");
return g.V()
.has(label,"uuid",uuid)
.bothE()
.otherV()
.path()
.by(__.valueMap(true))
.toList()
}
getNeighbors("host", "host1")
.then(results => {{{ }}
console.log("Sending results..."+JSON.stringify(results));
});
{code}
OUTPUT:
{code:java}
> getNeighbors host[host1]
Sending
results...[{"labels":[[],[],[]],"objects":[{},{},{}]},{"labels":[[],[],[]],"objects":[{},{},{}]},{"labels":[[],[],[]],"objects":[{},{},{}]}]
{code}
Same query from console:
{code:java}
gremlin>
g.V().has("host","uuid","host1").bothE().otherV().path().by(valueMap(true)).toList()
==>path[
{id=1, label=host, model=[D-host], manufacturer=[Dell], name=[host1],
uuid=[host1]}, {id=0, label=MOUNTED_IN,
uuid=6ca30477-80e2-4df6-9e00-10adddc0c04f, name=host1 to chassis1, slots=1},
{id=0, label=chassis, model=[D-chassis], manufacturer=[Dell], name=[chassis1],
uuid=[chassis1]}]
==>path[{id=1, label=host, model=[D-host], manufacturer=[Dell], name=[host1],
uuid=[host1]}
, {id=20, label=MOUNTED_IN, uuid=ea0b7e49-9738-4624-86e7-ba57de873120, name=vm1
to host1},
{id=22, label=vm, name=[vm1], uuid=[vm1]}

to host1},
{id=21, label=vm, name=[vm2], uuid=[vm2]}
]
{code}
If I remove the .by(__.valueMap(true)) from the javascript query, I receive
the following valid output:
{code:java}
> getNeighbors host[host1]
Sending results...[{"labels":[[],[],[]],"objects":[
{"id":1,"label":"host"}
,{"id":0,"label":"MOUNTED_IN","outV":1,"inV":0,"properties":{}},{"id":0,"label":"chassis"}]},{"labels":[[],[],[]],"objects":[
{"id":1,"label":"host"}

the following valid output:
