Upgrade to version 2.102.2.20 has broken code

Question

Hi everyone,
The code below worked using ODAC 2.102.2.10 but now fails with version 2.102.2.20:
int rows = 0;
using (OracleConnection con = new OracleConnection(Configuration.Instance.ConnectionString))
con.Open();
// Create and set up the command.
OracleCommand cmd = new OracleCommand("", con);
cmd.XmlCommandType = OracleXmlCommandType.Insert;
// The following call sets the command text to an xml representation
// of the object to be stored in the database, including a set of
// points in the sdo_geometry type 'geo_position'
cmd.CommandText = CreateXMLText(link);
// Columns to be inserted...
string[] UpdateColumnsList = new string[10];
UpdateColumnsList[0] = "ID";
// etc...more columns corresponding to xml
UpdateColumnsList[9] = "GEO_POSITION";
// Set the XML save properties.
cmd.XmlSaveProperties.RowTag = "ROW";
cmd.XmlSaveProperties.Table = "LINK_INSTANCE";
cmd.XmlSaveProperties.UpdateColumnsList = UpdateColumnsList;
// Do the insert.
rows = cmd.ExecuteNonQuery();
// Clean up.
cmd.Dispose();
con.Close();
It throws this error:
"Object reference not set to an instance of an object."
Apart from reverting to the previous version, does anyone have any other suggestions please?

Hi,
Just to make it easier if anyone wants to help, here's an example using the scott + tiger schema, user and password. Exact same problem.
static void InsertDept()
string sDeptXML =
"<?xml version=\"1.0\"?>" +
"<ROWSET>" +
"<ROW>" +
"<DEPTNO>1</DEPTNO>" +
"<DNAME>Testing</DNAME>" +
"<LOC>Suffolk</LOC>" +
"</ROW>" +
"</ROWSET>";
using (OracleConnection con = new OracleConnection("Data Source=BT;User Id=Scott;Password=Tiger;"))
con.Open();
OracleCommand cmd = new OracleCommand("", con);
cmd.XmlCommandType = OracleXmlCommandType.Insert;
cmd.CommandText = sDeptXML;
string[] UpdateColumnsList = new string[3];
UpdateColumnsList[0] = "DEPTNO";
UpdateColumnsList[1] = "DNAME";
UpdateColumnsList[2] = "LOC";
cmd.XmlSaveProperties.RowTag = "ROW";
cmd.XmlSaveProperties.Table = "DEPT";
cmd.XmlSaveProperties.UpdateColumnsList = UpdateColumnsList;
try
int nRowsAffected = cmd.ExecuteNonQuery();
catch (Exception e)
Console.WriteLine(e.Message);
cmd.Dispose();
con.Close();
The stack trace starts like this...
at Oracle.DataAccess.Client.OracleParameter.SetStatus(Int32 arraySize)
at Oracle.DataAccess.Client.OracleParameter.PreBind(OracleConnection conn, IntPtr errCtx, Int32 arraySize)
at Oracle.DataAccess.Client.OracleCommand.ExecuteXmlSave()
at Oracle.DataAccess.Client.OracleCommand.ExecuteNonQuery()
Well, hey, this code used to work!
