-----------------------------------------
Summary: PathRetractionStrategy can easily break VertexPrograms
Key: TINKERPOP-1424
URL: https://issues.apache.org/jira/browse/TINKERPOP-1424
Project: TinkerPop
Issue Type: Bug
Components: process
Affects Versions: 3.2.1
Reporter: Daniel Kuppitz
I just ran into an issue where I had to remove {{PathRetractionStrategy}} from
the traversal strategies. The traversal was something like this:
{code}
g.V().out().as("a").out().program(myVertexProgram)
{code}
..and {{myVertexProgram}} tried to access the path label "a". This doesn't work
if {{PathRetractionStrategy}} is used.
I think we need to extend VertexPrograms, like in TINKERPOP-1280. If a
VertexProgram has a {{LABELED_PATH}} requirement, it should also provide
information about which labels it needs access to.
