[Quickfix-developers] catch getField business rejects

[John G. <joh...@wa...>]

Hi there,

The more different Fix engines I connect to, the more I see that no one 
cares about conditionnaly required fields. So very often, I use a 
getField() method that fails and sends a Business Reject. The counterparty 
then complains about this (well of course, they don't send the correct 
data so it's only logical they should complain when they are told they 
don't). Anyway, I'd rather not have to always use the 
if(isSetField(...)){getField()...} construct when I *know* the message is 
supposed to have the tag, but at the same time, manage the error myself. 

What would be the central point for catching which exception to do that ? 
The fromApp() method catching FIX::FieldNotFound ?

TIA
