[jira] [Created] (TINKERPOP-1415) Vertex programs that rely on getting path parameters can't work

-------------------------------------

             Summary: Vertex programs that rely on getting path parameters can't work
                 Key: TINKERPOP-1415
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-1415
             Project: TinkerPop
          Issue Type: Bug
          Components: process
    Affects Versions: 3.2.1
            Reporter: Bryn Cooke


Recently some of our vertex programs have started failing.
They rely of being able to retrieve an element out of the path.
However, whereas this used to work now the path element isn't there anymore.

The root cause is that path retraction doesn't know that the vertex program is interested in the path and therefore culls out parameter.

I can understand why it does this, but there seems to be no way of exposing the vertex program path requirements such that PathRetractionStrategy can pick them up and do the right thing.

I tried hacking together a solution by making ProgramVertexProgramStep implement Scoping. This did fix the issue, but I am not confident that this is the way to go.
