Because you uncovered a defect or missing functionality in this API :-)
Seriously, indeed, you have found a defect. Currently .NET API is not handling
assigning a status history value *unless* supplied as a string (i.e. an encoded
format string value). However unfortunately the utility method (within
StatusHistory class in this API) for encoding the status history is marked
internal, so I am attaching a simple implementation of this method for your
convenience:
/// <summary>
/// Encode the status history content to string representation as per AR
System data file encoding scheme
/// </summary>
/// <returns></returns>
string Encode(StatusHistory sh)
{
string encoded = "";
System.DateTime unixEpoch = new System.DateTime(1970, 1, 1, 0, 0, 0);
foreach (StatusHistoryItem item in sh)
{
if (item.Time != System.DateTime.MaxValue)
{
System.TimeSpan span = item.Time - unixEpoch;
encoded += span.TotalSeconds;
encoded += (char)4;
encoded += item.User;
}
encoded += (char)3;
}
return encoded;
}
Now, paste this method in your class & convert your status history value
addition to this statement below:
(BMC.ARSystem.StatusHistory)entry[15];
fieldValueList.Add(15, Encode(sh));
See how it behaves now....

Subject: Problem with Status History in .NET API
Hi list,
Working in C#, I am trying to merge a record, including the status
history in the list of updated fields.
I create a FieldValueList:
BMC.ARSystem.FieldValueList fieldValueList = new
BMC.ARSystem.FieldValueList();
At one point, I execute the following statements:
BMC.ARSystem.FieldValueList entry =
_server.GetEntry(currentSchemaName, entryId);
BMC.ARSystem.StatusHistory sh =
(BMC.ARSystem.StatusHistory)entry[15];
fieldValueList.Add(15, sh);
I Check that sh is a Status History object containing the expected values.
After the Add statement, I check the value of fieldValueList[15]. It is
set to System.DBNull !!
Does anyone know the reason why I cannot set the Status History when
trying to do a merge operation ?
Thanks
André
