update Gephi Plugin portal link
Added lucene and neo4j-index for Schema Index dependency
Added Transactions around the Neo4jDelegateProviderImpl operations
TODO Still Error in Gephi Runtime
I have zero knowledge of Gephi internals and no experience with Netbeans so I'm lost here.
Seems to be that the `value` in one of the AttributeValueImpl is not a Long (Node-Id) but a String
probably somewhere the origin wrongly set as DELEGATE
from AttributeValueImpl.getValue()

result = attributeValueDelegateProvider.getNodeAttributeValue(value, column);
} else {

Exception:

upgrade to Neo4j 2.0.1 Tested and working fine after the 2 additional commits. Note: it's necessary to have latest Gephi 0.8.2 updates to fix an old Gephi bug.

It works but the field seems to be some kind of non-regular field. Neither can I use it to partition the data nor is it exported when e.g. saving the data to graphml |

Thanks for checking this out! I created Node labels as a field of type stringlist, as a node may have multiple labels. Currently, Fields of Type stringlist are not that well supported (see this forum thread as well). |
