{{Quickfixn}} FromAdmin been called when receiving custom messages

[Grant Birchmeier]

In the default FIX message dictionary, "n" is actually an admin message
type (XMLnonFIX message).

If your counterparty had picked any letter/number not in "0A12345n," you'd
be fine.  But they picked "n".

In the QF/n code, the list of admin messages is hardcoded, because we don't
expect counterparties to mess with those types.  And in our defense, they
usually don't.

"Should I just check for this message type in FromAdmin and call Crack()
when I find it?"
Yep, I think this would be a perfectly fine way to workaround it.
Alternately, you can hack the source and take the "n" out of the function
that I linked above and rebuild the engine, but I wouldn't do that if I was
in your shoes :)
