But then the node with the outgoing edge is node 'nid2' and the one with the incoming edge is 'nid1'. Thus I think that the following lines\r\n\r\n    addToOutgoing(nid1, eid);\r\n    addToIncomming(nid2, eid);\r\n\r\nshould be \r\n\r\n    addToOutgoing(nid2, eid);\r\n    addToIncomming(nid1, eid);\r\n\r\nOr do I understand something wrong?\r\n\r\nBest,\r\nSebastian"}}
