Re: [Quickfix-developers] Enumerating all repeating groups in a FIX message

[Alex M. <ale...@ya...>]

Dale,

Thanks - though I still have a couple of questions...

In your [begin group entry] block, it seems to me there's some missing code - "groupMap" is not assigned any value before you recursively call decodeFieldMap.

Also, in C# (which is what I'm using right now), the compiler complains that it can't convert QuickFix.Group to QuickFix.FieldMap - and I can't see any methods that would allow me to retrieve the FieldMap from a Group. How do I achieve this bit?

Thanks again.
Alexandros
