<p>Hi,<o:p></o:p></p>
<p>when receiving the hereunder allocation instruction (parties were renamed so length and hash are no longer consistent) on our quickfix server, an exception was thrown (see hereunder complete stack) , due to the bad index search in a dictionary.
<br>
Exception is thrown from file DataDictionary\DataDictionary.cs in method <br>
public void Iterate(FieldMap map, string msgType), line 213<br>
Faulty Code section is :<br>
// check contents of each group<br>
foreach (int groupTag in map.GetGroupTags())<br>
{<br>
for (int i = 1; i <= map.GroupCount(groupTag); i++)<br>
{<br>
Group g = map.GetGroup(i, groupTag)<br>
DDGrp ddg = this.Messages[msgType].GetGroup(groupTag);<br>
// throw an exception if key not found<br>
IterateGroup(g, ddg, msgType)<br>
}<br>
}<br>
This loop is looking for groupTag 167 in Messages["J"] and this throws the exception.<br>
Adding a condition<br>
if (Messages[msgType].Groups.ContainsKey(groupTag)) <br>
before the GetGroup() line solves the issue, but i wonder if it might hide a deeper issue ?<o:p></o:p></p>
