ExecutionReport with added field is erroneously rejected

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Add tag 204 to FIX42.xml, message type 8 ("ExecutionReport"), required = Y.
2.Configure an initiator and acceptor to have one FIX 4.2 session.  Connect 
them.
3.From the Acceptor, send an ExecutionReport.  It will get rejected by the 
initiator with the message:

What is the expected output? What do you see instead?

I would expect it would work.  Instead, the initiator rejects with this message 
(i.e., this is what the acceptor window shows):

8=FIX.4.2
9=123
35=3
34=182
49=INIT
52=20150423-17:15:34.668
56=ACCEPT
45=183
58
=Tag not defined for this message type
371=204
372=8
373=2
10=121


It appears that tag 204 is not being understood by the initiator?

What version of the product are you using? Using which Java version? On
what operating system?

QuickFIX Messenger 2.0
java version "1.7.0_65"
OpenJDK Runtime Environment (fedora-2.5.2.5.fc20-x86_64 u65-b17)
OpenJDK 64-Bit Server VM (build 24.65-b04, mixed mode)

Running on Fedora fc20

Please provide any additional information below.

Perhaps I am configuring something wrong?  This seems like such a basic thing 
to break.

BTW I forgot to mention, in step #3 to reproduce the issue, make sure to 
correctly populate all fields :)
