--------------------------------------
Summary: GraphML Export Fails with List Cardinality
Key: TINKERPOP-1935
URL: https://issues.apache.org/jira/browse/TINKERPOP-1935
Project: TinkerPop
Issue Type: Bug
Components: io
Affects Versions: 3.3.2
Reporter: James Baker
Exporting to GraphML throws an error if there are nodes with a List Cardinality
and multiple values set for a property. This works fine when exporting to
GraphSON.
The exception thrown is:
{{java.lang.IllegalStateException: Multiple properties exist for the provided
key, use Vertex.properties(name)}}{{at
org.apache.tinkerpop.gremlin.structure.Vertex$Exceptions.multiplePropertiesExistForProvidedKey(Vertex.java:179)}}
{{ at
org.apache.tinkerpop.gremlin.tinkergraph.structure.TinkerVertex.property(TinkerVertex.java:75)}}
{{ at
org.apache.tinkerpop.gremlin.structure.io.graphml.GraphMLWriter.writeVertices(GraphMLWriter.java:315)}}
{{ at
org.apache.tinkerpop.gremlin.structure.io.graphml.GraphMLWriter.writeGraph(GraphMLWriter.java:193)}}
