{{Quickfixn}} Errors with Repeating groups for Custom Message

[Grant Birchmeier]

First of all, this group structure makes little sense.  Your PartyIDs group
doesn't contain anything besides the subgroup; why do the subgroups need to
be wrapped in a PartyID group at all?  In fact, I could write an alternate
msg definition that would be functionally identical to yours, but without
the nesting:

<message name=
​"
CustomMessage" msgtype="U14" msgcat="app">
​    ​
<
​
field
n
ame="NoPartyIDs" required="Y"
​/​
>
​    ​
<group name="NoPartySubIDs" required="Y">
​        ​
<field name="PartySubID" required="Y" />
​        ​
<field name="PartySubIDType" required="Y" />
​    ​
</group>
</group>


Do you see what I mean?  The extra nesting doesn't give you anything.  Why
have a Party without a PartyID?

*As to the actual error:  *I'm pretty sure the error is because QF/n is
looking for a non-group field positioned at the start of NoPartyIDs (before
the subgroup).  All group elements are required to include the first field
of the definition (typically referred to as the "delimiter" field).

But your group definition doesn't have a first field -- the first field is
a subgroup.  This is unlike all standard FIX groups.

I suppose, technically, you could argue that the engine is misbehaving
because it's making wrong assumptions about your message -- it's looking
for a delimiter field that your NoPartyIDs group doesn't actually define.
However, I'd argue instead that your group definition might be invalid:
standard FIX groups don't look like this, so yours shouldn't either.

This definition would make more sense:

<message name="CustomMessage" msgtype="U14" msgcat="app">
​    ​
<
​group
 n
ame="NoPartyIDs" required="Y"
​​
>

<field name="PartyID" required="Y"/>
        <!-- add PartyIDSource and PartyRole too if you like -->
​    ​
<group name="NoPartySubIDs" required="Y">
​            ​
<field name="PartySubID" required="Y" />
​        ​
<field name="PartySubIDType" required="Y" />
​    ​
</group>
    </group>
</group>

​
Are you
​able to alter the
definitions
​ like I'm suggesting​
, or are you stuck working with a counterparty who is doing stupid things?
