OIndex<?> index = this.graph.getRawGraph().getMetadata().getIndexManager().getIndex(indexName); OIndexKeyCursor cursor = index.keyCursor();
When i call this the cursor is null. System.out.println(index.getFirstKey()); getFirstKey() is also null. The index is created, filled and working. Its the correct indexname because: System.out.println(index.getDatabaseName()); System.out.println(index.getName()); System.out.println(index.getKeySize()); System.out.println(index.getSize()); System.out.println(index.getType()); prints the correct results.
