----------------------------------------------
Summary: Issue with bindings in strategies and lambdas
Key: TINKERPOP-1898
URL: https://issues.apache.org/jira/browse/TINKERPOP-1898
Project: TinkerPop
Issue Type: Improvement
Components: python, server
Affects Versions: 3.3.1
Reporter: Jean-Philippe Braun
Attachments: bug.py
I'm trying to use bindings in a traversal strategy like:
{code:java}
graph = Graph()
g =
graph.traversal().withRemote(DriverRemoteConnection('ws://localhost:8182/gremlin',
'g'))
g = g.withStrategies(
SubgraphStrategy(vertices=__.has('foo', ('b', 5)))
){code}
This works unless there is a use of lambda in the traversal:
{code:java}
g.V().toList() # will work
g.V().filter(lambda: "true").toList() # this will not{code}
Here is the full TB on the server:
{code:java}

I've tried also to use python lambdas but it gets worse, I get the
error:
{code:java}
GremlinServerError: 599: NameError: name 'TraversalStrategy' is not defined
in <script> at line number 1{code}
