Description

Fix 4.4 defines XML Message (message type = 'n') that contains XmlData. There are XmlData and XmlDataLen classes in QuickFIX/J, but there is no actual class for XmlMessage. As a result calling MessageFactory.create(BEGIN_STRING, 'n') returns null

I think the problem lies within the specification of the XmlMessage itself. In FIXimate (http://www.fixtradingcommunity.org/FIXimate/FIXimate3.0/) the MsgType n is only specified having a header and a trailer, but no body fields. When adding this information to the data dictionary and regenerating the code the MessageFactory returns a message but when adding fields and validating the message the error "No fields found" is thrown by the DataDictionary. So it seems that the XmlMessage cannot be completely supported.
Another point is that by definition of the FIXimate msgType n is an admin message but QuickFIX/J currently will not treat it as admin message (see MessageUtils.isAdminMessage()). I do not know if that will cause additional problems.
