I ran into a (System.NullReferenceException: Object reference not set to an
instance of an object) from FesTransaction.Commit, and I have no clue what's
happenning... as my code from BeginTransaction to Commit is not-threaded...
public void Commit()
{
this.CheckTransactionState();
lock (this.db)
{
// Clear the status vector
this.ClearStatusVector();
int trHandle = this.handle;
db.FbClient.isc_commit_transaction(this.statusVector, ref trHandle);
this.handle = trHandle;
this.db.ParseStatusVector(this.statusVector);
this.db.TransactionCount--;
if (this.Update != null)
{
this.Update(this, new EventArgs()); <-- Blows up here,
this.Update == null!?!? Suspect this is a threading issue? Any idea how this
happenned? (Nothing in my code references FesTransaction.Update and whole
BeginTransaction/Commit is not-threaded)
}
this.state = TransactionState.NoTransaction;
}
}
