Re: [Quickfix-developers] session id's and arca fix certification

You need to specify in the context of the FIX version and message,=20
since groups change definitions between FIX versions.

So for instance FIX42::NewOrderSingle::NoTradingSessions group;
group.set( FIX::TradingSessionId("P1" ) );
message.addGroup( group );
group.set( FIX::TradingSessionID("P2") );
message.addGroup( group );
group.set( FIX::TradingSessionID("P3") );
message.addGroup( group );

Field 386, NoTradingSessions, will automatically be calculated and set=20=

for you.
