Quickfixn-标签出现的次数超过一次

Question

I'm having an issue with Quickfixn and I'm hoping someone with more experience working with it can shed some light on an issue I'm facing. For some reason, messages are getting rejected by the QuickFix engine because of repeating tags... I expect to have repeating tags and so I set the UseDataDictionary flag = Y in my config file but messages are still getting rejected. Has anyone experienced a similar issue ?

The message I'm receiving looks like :

8=FIXT.1.1 9=421 35=AE 34=8 1128=8 49=XXX 56=YYY 52=20130501-15:45:53 552=1 54=2 37=130501-5 11=NOREF 826=0 78=1 79=default 80=1000000.00 5967=12167800.00 453=4 448=ITXT 452=3 447=D 448=TEST 452=1 447=D 448=LMEB 452=16 447=D 448=FRTB 452=11 447=D 571=6718487 150=F 32=1000000.00 15=USD 1056=12167800.00 31=12.1678 194=12.1678 195=0 64=20130503 63=0 60=20130501-00:00:00 75=20130501 1057=Y 460=4 167=FOR 65=SP 55=USD/MXN 10=203

my config file looks like this:

[DEFAULT]
ConnectionType=initiator

SocketReuseAddress=Y
FileStorePath=D:\Store
FileLogPath=D:\Log

[SESSION]

SocketConnectPort=8443

Any help would be greatly appreciated! Thank you.

Answer 1

Often this happens because there is a field in a repeating group that is not specified in the DataDictionary. The parser sees the field and assumes the repeating group has ended. It continues parsing fields as if they are not part of a group. If it sees a duplicate field in this context, the parser will report an error.

You may clone and modify FIX Data Dictionary (D:\\Interface\\FIX50SP1.xml) to fit your needs, if you need to process "invalid" messages. Or you may disable message validation.
