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()
````
            } else if (AttributeUtilsImpl.getDefault().isNodeColumn(column)) {
                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.
