Re: [Quickfix-developers] Question about customized group

Hi,

There is no xsl for NewOrderSingle, the heavy job is made by ruby scripts.
IMHO, it should work for your case too. I can't see a reason why not.
Anyway, you can change the NewOrderSingle.h yourself, but the scripts exist
to automate this process.

Another solution I used to adopt in the past, when I did not know how to use
the scripts, required some more coding to create the group and add it to the
FIX::Message, like example bellow:

// Declare a group like the following:

class NoBTSClients : public FIX::Group
{
public:
    NoBTSClients() : FIX::Group(BTS::FIELD::NoBTSClients,
                       BTS::FIELD::BTSClient,
                       FIX::message_order(BTS::FIELD::BTSClient,
FIX::FIELD::BeginString, BTS::FIELD::BTSClientStatus, 0))
    {}
};

// use it in a FIX::Message
FIX::Message statusResponse;
NoBTSClients aClientStatus;
aClientStatus.setField(BTS::FIELD::BTSClient,
curIter->getTargetCompID().getValue() );
aClientStatus.setField(FIX::FIELD::BeginString,
curIter->getBeginString().getValue() );
std::stringstream textstream;
textstream << iStatus;
aClientStatus.setField(BTS::FIELD::BTSClientStatus, textstream.str());
statusResponse.addGroup(aClientStatus);

But, if you want the most elegant solution... maybe if you submit your
modified FIX42.xml, maybe I can help you with the scripts results.
