QuickFIX / n：查询组时出现FieldNotFoundException

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

This is the FIX message log:

And finally, the acceptor settings:

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:
