Thread: [Quickfix-users] message rejected: required tag missing (with user-defined tag)

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

I have defined several user-defined tags, the type-safe way, in c#. You 
will find the definitions inlined below. There is one tag that causes a 
rejection required tag missing error when the target tries to ACK my new 
orders - that tag is IdTrade, seen in the code snippet directly below. 
None of the other user-defined tags causes this error. When I comment 
out the code that sets idTrade, the error goes away.

What is different about that tag? I even changed its tag number, and 
tried changing the order in which I set the fields, and the issue still 
happens. How does a user-defined tag become to be considered a required 
tag by quickfix???

            //custom fields
            IdTrade idTrade = new IdTrade( tr.idTRADE );
            order.setField( idTrade );

            WTR1 wtr1 = new WTR1( (double)tr.WTR_1 );
            order.setField( wtr1 );

            Eliq1 eliq1 = new Eliq1( (double)tr.ELiq_1 );
            order.setField( eliq1 );

            Signal signal = new Signal( tr.Signal );
            order.setField( signal );

            DWRPV0 dwrpv0 = new DWRPV0( (double)tr.DWRPV0 );
            order.setField( dwrpv0 );

            DWRPV1 dwrpv1 = new DWRPV1( (double)tr.DWRPV_1 );
            order.setField( dwrpv1 );

            V61 v61 = new V61( (double)tr.V_6_1 );
            order.setField( v61 );
