[Quickfix-developers] repeating group - saying field not available

[Rick L. <ric...@gm...>]

Greetings,

I'm having trouble retrieving a repeating group and was hoping someone 
could nudge me in the right direction.  I'm attempting to grab 
SecurityDefinition.NoLegs group.  Below is a snippet of the FIX message:


9787=1
*555=2*
600=[N/A]
623=1
602=980018
603=8
624=1
600=[N/A]
623=1

602=980023
603=8
624=2

tag 555 is the NoLegs tag, and you can see here the value is 2, followed 
by both entries in the repeating group (colored blue and orange).  Here 
is how I'm attempting to retrieve the group:

public override void onMessage(SecurityDefinition message,
                                QuickFix.SessionID session)
{
    QuickFix.NoLegs noLegs = new NoLegs();
    message.getField(noLegs);
    int numLegs = noLegs.getValue();
   
    for (uint i = 0; i < numLegs; i++) {
        QuickFix44.SecurityDefinition.NoLegs group =
                new QuickFix44.SecurityDefinition.NoLegs();  
        _message.getGroup(i + 1, group);_
...

The underlined red area is where I'm getting the FieldNotFound error.  
What is missing from the FIX message (or what do I need to do 
additionally) to be able to grab this group?  If I can't use the 
type-specific QuickFix44.SecurityDefinition.NoLegs class, is there a way 
I can more manually extract this group?

Thanks in advance,
Rick

After looking further into my issue, I believe it has to do with 
improperly /creating /the message.  I'm attempting to generically create 
a group (not knowing, necessarily, /which /repeating group it is 
(meaning I don't know if it's the NoMDEntries, or NoLegs, etc. group).  
I'm given the message field by field, and I had been just adding the 
fields as they came (so even if a field was part of a repeating group, 
I'd just keep calling message.setField() for each time; each time it 
would overwrite the previous field.

So now I'm trying to properly construct the message using the Group 
class, however I'm having a hard time getting the length field to 
automatically be created like it is when you use type-specific groups.  
In other words, here are the messages I get, in order, from the exchange:

1.) [555] = 2
2.) [600] = [N/A]
3.) [623] = 1
4.) [602] = 980018
5.) [603] = 8
6.) [624] = 1
7.) [600] = [N/A]
8.) [623] = 1
9.) [602] = 980023
10.) [603] = 8
11.) [624] = 1

How could I construct a generic Group object such that it includes the 
tag [555]?  If I do the following QuickFix doesn't know that both groups 
belong to the same sequence.  Can groups be constructed generically?

QuickFix.Group group1 = new QuickFix.Group(1, 0);
  group1 .setField(600, "[N/A]")
  group1 .setField(623, "[N/A]")
  ...

QuickFix.Group group2 = new QuickFix.Group(1, 0);
  group2 .setField(600, "[N/A]")
  group2 .setFi eld(623, "[N/A]")
  ...

message.addGroup(group1);
message.addGroup(group2);

Thanks,
Rick
