QuickFIX/n: FieldNotFoundException when querying group - fix-protocol

Question

I'm currently using QuickFIX/n to build an acceptor service, and I've built an initiator to test the acceptor. I suspect the error I get is due to a bug in the acceptor because the same error occurs with a message that someone else is sending to the service.
In the initiator I build and send an AllocationInstruction as follows:
var fix44Message = new QuickFix.FIX44.AllocationInstruction(
new AllocID(request.Info.AllocationID), EnumHelpers.ParseAllocationTransactionType(request.Info.AllocationTransactionType), EnumHelpers.ParseAllocationType(request.Info.AllocationType),
new AllocNoOrdersType(AllocNoOrdersType.EXPLICIT_LIST_PROVIDED), EnumHelpers.ParseSide(request.Info.Side), new Symbol(request.Info.Symbol), new Quantity(request.Info.Quantity),
new AvgPx(request.Info.AveragePrice), new TradeDate(request.Info.TradeDate.ToString("yyyyMMdd")))
{
SecurityID = new SecurityID(request.Info.SecurityID),
SecurityIDSource = new SecurityIDSource(request.Info.SecurityIDSource),
SecurityExchange = new SecurityExchange(request.Info.SecurityExchange),
Issuer = new Issuer(request.Info.Issuer),
Currency = new Currency(request.Info.Currency),
TransactTime = new TransactTime(request.Info.TransactTime),
SettlDate = new SettlDate(request.Info.SettlementDate.ToString("yyyyMMdd")),
GrossTradeAmt = new GrossTradeAmt(request.Info.GrossTradeAmount),
NetMoney = new NetMoney(request.Info.NetMoney)
};
var group = new QuickFix.FIX44.AllocationInstruction.NoOrdersGroup
{
ClOrdID = new ClOrdID(order.ClOrdID),
OrderID = new OrderID(order.OrderID),
OrderQty = new OrderQty(order.Quantity)
};
fix44Message.AddGroup(group);
In this specific case the message is created with exactly one order group.
In the acceptor I try get the order-groups as follows:
public void OnMessage(QuickFix.FIX44.AllocationInstruction allocation, SessionID sessionID)
{
Console.WriteLine("Order count: " + allocation.NoOrders.getValue());
var orderGroup = new QuickFix.FIX44.AllocationInstruction.NoOrdersGroup();
allocation.GetGroup(1, orderGroup);
info.Orders.Add(new AllocationInstructionOrder
{
ClOrdID = orderGroup.ClOrdID.getValue(),
OrderID = orderGroup.OrderID.getValue(),
Quantity = orderGroup.OrderQty.getValue()
});
}
allocation.NoOrders has a value of 1 as expected. However, when GetGroup() is called with an index of 1 (first group), I get
QuickFix.FieldNotFoundException occurred

The C# code above is based on the example on the QuickFIX/n site.
Any ideas?

Answer 1

After downloading the source code for quickfix/n and debugging against it I finally found the cause of the problem!
The acceptor did not interpret the message properly because it did not create a group for the NoOrders (73) tag. The data-dictionary map for looking up group tags was empty, because I used UseDataDictionary=N in my settings.
Changing the acceptor to use a data dictionary solved the problem.
Here is my updated settings string:
[DEFAULT]
SenderCompID=BAOBAB
UseDataDictionary=Y
