NoSuchMethodError on RestTypedTraverser

[kouphax]

The following traversal code is throwing an error for me,

organisation.doTraverse[DocumentLink](follow(BREADTH_FIRST) -<- "ATTACHED_TO", 1 , ReturnAllButStartNode)

However the alternative options are fine,

organisation.doTraverse[DocumentLink](follow(BREADTH_FIRST) -<- "ATTACHED_TO", 1 , "true")

Is there something I am doing wrong in the first sample that is stopping me from getting all but the start node? The error is below,

Wrong Neo4j version?

I thought this but I'm using 1.7 with the 1.8-SNAPSHOT dependency.

They removed Traversal.returnAllButStartNode() from Neo4j 1.8...
I will try to fix that in 0.2.0-M2-SNAPSHOT

[kouphax]

Is it possible to use evaluators in the current version or will that need to be added?

There is no specific interace in neo4j-scala for Evaluators. I mapped the "old" Traverser to my TypedTraverser.
Ideas and code appreciated :-)

But I uploaded 0.2.0-M2-SNAPSHOT version with a Neo4j 1.8 dependency (without profiles). Hope that helps.
