[Quickfix-developers] quickfix rejecting BZ message as value out of range

[Shawn M. <rob...@gm...>]

My application is the initiator and I send a MassActionRequest to cancel
all orders. The orders are canceled but my quickfix client rejects the
incoming BZ message.

8=FIXT.1.19=12835=334=549=SHAZZ52=20160916-21:44:19.00056=TESTA45=458=Value
is incorrect (out of range) for this tag371=35372=BZ373=510=017

But FIX50SP2.xml has

<message name='OrderMassActionReport' msgcat='app' msgtype='BZ'>
   <field name='ClOrdID' required='N' />
   <field name='SecondaryClOrdID' required='N' />
   ...

and

  <field number='35' name='MsgType' type='STRING'>
   <value enum='0' description='HEARTBEAT' />
   ...
   <value enum='BZ' description='ORDERMASSACTIONREPORT' />

All other message flows work properly, I receive ExecutionReport messages,
etc.

So I'm at a loss. Any help from developers who have run into a similar
situation is much appreciated!
