Group parsing problem

[TomasVetrovsky]

Group gets corrupted when parsing message from string and MessageFactory is not set or MessageFactory fails to create typed Group. Parsing fails on the second instance of the group.

Grp must be reset to null when the last instance of group was added to fieldMap.

Message.SetGroup method:
...
// Create a new group!
if (msgFactory != null)
grp = msgFactory.Create(Message.ExtractBeginString(msgstr), Message.GetMsgType(msgstr), grpNoFld.Tag);

//If above failed (shouldn't ever happen), just use a generic Group.

//********** grp already contains first instance of group.
if (grp == null)
grp = new Group(grpNoFld.Tag, grpEntryDelimiterTag, order);

I need more context to know that this is an engine problem and not a problem with your application.

• What is the message being parsed?
• Is that message coming from a counterparty session or are you creating it?
• Are you sure your data dictionary is correct?
• What do you mean by "Grp must be reset to null..."?

Correction is under commit TomasVetrovsky@7d775ce

We do not use message factory at all. We have different counterparties who use diferent dataDictionaries (different custom fields). If we use MessageFactory we would need different binaries for each counterparty. You can see the problem in the commit.

I think same as #179 and #162
