Issue with IN parameter of Oracle Procedure returning two RefCursors...

Question

Hi all,
I'm having a nightmare with an Oracle procedure that takes one input parameter and returns two RefCursors as outputs. I recently got help in this forum getting a procedure to work that took no inputs but returned two refcursors and that's still working fine. So, for my current issue I have a procedure defined as follows:
PROCEDURE getQueueInfo(domainKey char, importQueues OUT ODPNet.refcur, exportQueues OUT ODPNet.refcur) IS
  BEGIN
    OPEN importQueues FOR SELECT
    source_key, source_applid,
    import_status(source_key) as status,
    time_added, time_processed
    FROM wm_import_source_header
    WHERE source_id = domainKey
    ORDER BY source_key DESC;
    OPEN exportQueues FOR SELECT
    h.source_key, d.source_applid,
    export_status(h.source_key) as status,
    d.source_wire_code, d.destination_wire_code, h.time_added,
    h.time_transmitted
    FROM wm_export_source_header h, wm_export_source_data d
    WHERE h.source_key = d.source_key
      and d.source_id = domainKey
    ORDER BY h.source_key DESC;
  END getQueueInfo;This is defined within a package called ODPNet as with my previous procedure and all works fine (I can execute within Oracle SQL Developer and it returns the expected results). Within my .NET application my code is as follows:
            try
                using (OracleConnection conn = new OracleConnection(connString))
                using (OracleCommand comm = new OracleCommand())
                    comm.CommandText = "ODPNet.getQueueInfo";
                    comm.CommandType = CommandType.StoredProcedure;
                    comm.Connection = conn;
                    OracleParameter domainKey = new OracleParameter();
                    OracleParameter importQueues = new OracleParameter();
                    OracleParameter exportQueues = new OracleParameter();
                    domainKey.OracleDbType = OracleDbType.Char;
                    importQueues.OracleDbType = OracleDbType.RefCursor;
                    exportQueues.OracleDbType = OracleDbType.RefCursor;
                    domainKey.Value = "UKBD72";
                    domainKey.Direction = ParameterDirection.Input;
                    importQueues.Direction = ParameterDirection.Output;
                    exportQueues.Direction = ParameterDirection.Output;
                    comm.Parameters.Add(domainKey);
                    comm.Parameters.Add(importQueues);
                    comm.Parameters.Add(exportQueues);
                    conn.Open();
                    comm.ExecuteNonQuery();
                    OracleDataReader dr1 = ((OracleRefCursor)importQueues.Value).GetDataReader();
                    OracleDataReader dr2 = ((OracleRefCursor)exportQueues.Value).GetDataReader();
                    if (dr1.HasRows)
                        while (dr1.Read())
                            result6 += dr1["source_applid"].ToString() + "<br>";
                    else
                        result6 += "No Rows";
                    if (dr2.HasRows)
                        while (dr2.Read())
                            result7 += dr2["source_applid"].ToString() + "<br>";
                    else
                        result7 += "No Rows";
            catch (Exception ex)
                result6 = ex.ToString();
            }The value I want to submit as the IN parameter of the procedure is "UKBD72". but I'm really not sure how to apply this and then return my two refcursors into separate datareaders (except for the input parameter stuff the code above is exactly what I did with the other procedure that returned two ref cursors and still works fine). When I run this code I get no errors, I just get told that each DataReader has no rows returned, which shouldn't be right.
Any help with this would be hugely appreciated.
Cheers,
Seb

Sorry folks, after staring at this over and over, eventually going to sleep and coming back to it with some fresh eyes I realised I was just being a complete idiot - I was feeding the procedure different data in the .NET app than I was when testing in Oracle SQL Developer. Low and behold once I gave it the right data it worked!
Silly me...
