----------------------------------------
    Description: 
I am using the Neo4jGraph with the following SubgraphStrategy:

{code}
SubgraphStrategy.build().vertexCriterion(has("isLatest", true)).create();
{code}

I have 2 traversals. This one working works:

{code}
Map<String, Long> languageCounts =  
searchResult.as("a").inE("isCreatedBy").outV().outE("hasWorkLanguage").inV().as("b").dedup("a",
 "b")
                  .has("wwlanguage_name").<String>groupCount()
        .by("wwlanguage_name").next();
{code}

This translates to:

{code}
[Neo4jGraphStep([],vertex)@[a], 
TraversalFilterStep([HasStep([isLatest.eq(true)])]), 
VertexStep(IN,[isCreatedBy],edge), 
TraversalFilterStep([AndStep([[EdgeVertexStep(IN), 
TraversalFilterStep([HasStep([isLatest.eq(true)])]), 
TraversalFilterStep([HasStep([isLatest.eq(true)])])], [EdgeVertexStep(OUT), 
TraversalFilterStep([HasStep([isLatest.eq(true)])]), 
TraversalFilterStep([HasStep([isLatest.eq(true)])])]])]), EdgeVertexStep(OUT), 
TraversalFilterStep([HasStep([isLatest.eq(true)])]), 
VertexStep(OUT,[hasWorkLanguage],edge), 
TraversalFilterStep([AndStep([[EdgeVertexStep(IN), 
TraversalFilterStep([HasStep([isLatest.eq(true)])]), 
TraversalFilterStep([HasStep([isLatest.eq(true)])])], [EdgeVertexStep(OUT), 
TraversalFilterStep([HasStep([isLatest.eq(true)])]), 
TraversalFilterStep([HasStep([isLatest.eq(true)])])]])]), 
EdgeVertexStep(IN)@[b], TraversalFilterStep([HasStep([isLatest.eq(true)])]), 
TraversalFilterStep([PropertiesStep([wwlanguage_name],property)]), 
DedupGlobalStep([a, b]), GroupCountStep(value(wwlanguage_name))]
{code}

This one fails:

{code}
Map<String, Long> languageCounts = 
searchResult.as("a").in("isCreatedBy").out("hasWorkLanguage").as("b")
                                                   .dedup("a", 
"b").has("wwlanguage_name")
      .<String>groupCount().by("wwlanguage_name").next();
{code}

This translates to:

{code}
[Neo4jGraphStep([],vertex)@[a], 
TraversalFilterStep([HasStep([isLatest.eq(true)])]), 
VertexStep(IN,[isCreatedBy],edge), 
TraversalFilterStep([AndStep([[EdgeVertexStep(IN), 
TraversalFilterStep([HasStep([isLatest.eq(true)])]), 
TraversalFilterStep([HasStep([isLatest.eq(true)])])], [EdgeVertexStep(OUT), 
TraversalFilterStep([HasStep([isLatest.eq(true)])]), 
TraversalFilterStep([HasStep([isLatest.eq(true)])])]])]), EdgeVertexStep(OUT), 
TraversalFilterStep([HasStep([isLatest.eq(true)])]), 
VertexStep(OUT,[hasWorkLanguage],edge), 
TraversalFilterStep([AndStep([[EdgeVertexStep(IN), 
TraversalFilterStep([HasStep([isLatest.eq(true)])]), 
TraversalFilterStep([HasStep([isLatest.eq(true)])])], [EdgeVertexStep(OUT), 
TraversalFilterStep([HasStep([isLatest.eq(true)])]), 
TraversalFilterStep([HasStep([isLatest.eq(true)])])]])]), EdgeVertexStep(IN), 
TraversalFilterStep([HasStep([isLatest.eq(true)])]), 
TraversalFilterStep([PropertiesStep([wwlanguage_name],property)]), 
DedupGlobalStep([a, b]), GroupCountStep(value(wwlanguage_name))]
{code}

The failing query misses the '@[b]' of the last EdgeVertexStep(IN).
