Re: [Quickfixj-users] Do you validate?

[Colin D. <co...@ma...>]

Robert,

For some sessions we do turn validate off because the other side is just 
too inconsistent. It is not our preferred approach, of course, because a 
lot of the code path assumes the FIX message is valid. In cases where we 
have to do this, we often will insert a little bit of code for that 
session to repair whatever the problem is to try to ensure the message 
is valid.
