"No Error" exception when printing report after Export

Question

Hello,
When calling a PrintToPrinter function after an Export of the same instance, the exception with the message "No Error" comes up.
This happens only for certain reports.
   at CrystalDecisions.ReportAppServer.Controllers.ReportSourceClass.GetLastPageNumber(RequestContext pRequestContext)
   at CrystalDecisions.ReportSource.EromReportSourceBase.GetLastPageNumber(ReportPageRequestContext reqContext)
   at CrystalDecisions.CrystalReports.Engine.FormatEngine.PrintToPrinter(Int32 nCopies, Boolean collated, Int32 startPageN, Int32 endPageN)
   at CrystalDecisions.CrystalReports.Engine.ReportDocument.PrintToPrinter(Int32 nCopies, Boolean collated, Int32 startPageN, Int32 endPageN)
   at FidelioCrystalNET.CrystalNET.Print() in CrystalNETLib.cs:line 127
Source      - "rptcontrollers.dll"
Same error also comes when calling either Refresh or VerifyDatabase methods.
Crystal Reports 2008 Runtime SP2 is installed. Reports using Oracle DB connection.
.NET code uses Framework 2.0
Anybody knows how to fix it?
Thanks

Hi Ludek,
I am able to reproduce the problem in a simple test code pure .NET (C#) application.
Here is the code:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;
namespace CrystalLibTest
    public partial class Form1 : Form
        private ReportDocument crpe;
        private ConnectionInfo connectionInfo;
        public Form1()
            InitializeComponent();
            ReportTest();
        public void Init(string service, string user, string password)
            connectionInfo = new ConnectionInfo();
            connectionInfo.ServerName = service;
            connectionInfo.DatabaseName = service;
            connectionInfo.UserID = user;
            connectionInfo.Password = password;
        private void SetDBLogonForReport(ConnectionInfo connectionInfo, ReportDocument reportDocument)
            Tables tables = reportDocument.Database.Tables;
            foreach (CrystalDecisions.CrystalReports.Engine.Table table in tables)
                TableLogOnInfo tableLogonInfo = table.LogOnInfo;
                tableLogonInfo.ConnectionInfo = connectionInfo;
                table.ApplyLogOnInfo(tableLogonInfo);
        private void SetDBLogonForSubreports(ConnectionInfo connectionInfo, ReportDocument reportDocument)
            Sections sections = reportDocument.ReportDefinition.Sections;
            foreach (Section section in sections)
                ReportObjects reportObjects = section.ReportObjects;
                foreach (ReportObject reportObject in reportObjects)
                    if (reportObject.Kind == ReportObjectKind.SubreportObject)
                        SubreportObject subreportObject = (SubreportObject)reportObject;
                        ReportDocument subReportDocument = subreportObject.OpenSubreport(subreportObject.SubreportName);
                        SetDBLogonForReport(connectionInfo, subReportDocument);
        private void AddCurrentValue(ParameterField field, object parameterValue)
            ParameterDiscreteValue parameterDiscreteValue = new ParameterDiscreteValue();
            parameterDiscreteValue.Value = parameterValue;;
            field.CurrentValues.Add(parameterDiscreteValue);
        private void setParameter(string parameterName, Object parameterValue)
            ParameterField field = crpe.ParameterFields[parameterName];
            if (field != null)
                AddCurrentValue(field, parameterValue);
        private void ReportTest()
            crpe = new ReportDocument();
            Init("SERVICE", "USERNAME", "PASSWORD");
            crpe.Load("c:\\temp\\report.rpt");
            SetDBLogonForReport(connectionInfo, crpe);
            SetDBLogonForSubreports(connectionInfo, crpe);
            setParameter("SP-PARAM1", "param_value1");
            setParameter("SP-PARAM2", 1111);
           /* about 20 different parameters are here */
            crpe.ExportToDisk(ExportFormatType.RichText, "c:\\temp\\export.rtf");
            setParameter("SP-PARAM1", "param_value1");
            setParameter("SP-PARAM2", 1111);
           /* about 20 different parameters are here */
            try
                crpe.PrintToPrinter(1, true, 1, 65535);
            catch (Exception e)
                MessageBox.Show(e.Message);
               /*here the error comes up*/
I also found that for some different reports, the error comes even when executing first time.
