Adding/Updating/Deleting items in a transaction throws null reference exception unless a query has been performed beforehand.

[holocentric-bmsnext]

e.g. when adding a new vertex into the database, if we don't fetch something from the database first a null reference exception will be thrown.

var transaction = database.Transaction;

//database.Select().From(new ORID("#0:0")); <- workaround code
.
.
.
transaction.Add(vertex);
transaction.Commit();

try this before using transaction:
database.DatabaseProperties.ORID = new ORID();
