> Key: TINKERPOP-2811
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2811
> Project: TinkerPop
> Issue Type: Bug
> Components: process
> Affects Versions: 3.4.0, 3.6.1
> Reporter: Cameron Smith
> Priority: Minor
>
> When using the ElementIdStrategy, if a traversal attempts to filter graph
> elements with multiple _has_ steps and the id filter is not the first
> property to be filtered on, then the reference to the element's id is not
> replaced with the custom id property during the ElementIdStrategy's mutation
> of the traversal:
> {noformat}
> gremlin> graph = TinkerGraph.open()
> ==>tinkergraph[vertices:0 edges:0]
> gremlin> g =
> graph.traversal().withStrategies(ElementIdStrategy.build().create())
> ==>graphtraversalsource[tinkergraph[vertices:0 edges:0], standard]
> gremlin> g.V().hasId("foo").has("name", "bar").explain()

> [TinkerGraphStep(vertex,[foo],[name.eq(bar)])]{noformat}
> In the above example, the first traversal shows the behavior when id
> filtering is done first, and the second traversal demonstrates the behavior
> when id filtering is not the first filtering step.
> This was reproduced on both TinkerPop 3.6.1 and 3.4.0.
> The current workaround is to ensure that when chaining _has_ steps together
> that the first filter on id, if filtering on id is required.
