[Quickfix-developers] quickfix message flow question

[Scott R. <sri...@fo...>]

The counterparty I am dealing with decided they need to alter the FIX
spec (added field here, changed field from required to conditional
there).

My intent was to utilize the fromApp() method (java implementation) to
add or subtract the required fields before cracking the message.
Unfortunately, this method is never reached when I receive the offending
messages.  The log shows the messages received and my rejection messages
sent, but the breakpoint in fromApp() never hits.  Does quickfix just
kick them out ahead of time (sending a reject message back to the
counterparty) and if so, is there some way to access the message instead
(my counterparty does not support reject messages.)  Any help would be
greatly appreciated.
