NullReferenceException on report.Render()

[alanj]

Hi all,

After looking at the WCF samples provided, I have implemented the same functionality in my current project which works successfully, except for when the report contains a Form.
When the report.Render() method is called a NullReferenceException occurs : "Object reference not set to an instance of an object".

I have used this same report file in the Sample WCF project provided and it works without any problems, and have recently updated the Stimulsoft version from 2011.2 to 2011.3.


I've included the code and stacktrace for the exception below,


StiReport report = new StiReport();
report.Load("filePath");

// Set Connection String
report.Dictionary.Databases.Clear();
report.Dictionary.Databases.Add(new StiSqlDatabase("DatebaseName", "DataBaseConnectionString"));

// Render report
report.Render(false);



at Stimulsoft.Base.StiExceptionForm..ctor(Exception exception)
at Stimulsoft.Base.StiExceptionProvider.Show(Exception exception)
at Stimulsoft.Report.Dialogs.StiWinDialogsProvider.RenderForm(IStiForm formControl)
at Stimulsoft.Report.Dialogs.StiWinDialogsProvider.Render(StiReport report, StiFormStartMode startMode)
at Stimulsoft.Report.Engine.StiRenderProviderV2.RenderFormsOnStart(StiReport report)
at Stimulsoft.Report.Engine.StiRenderProviderV2.Render(StiReport report, StiRenderState state)
at Stimulsoft.Report.Engine.StiReportV2Builder.RenderSingleReport(StiReport masterReport, StiRenderState renderState)
at Stimulsoft.Report.StiReport.RenderReport(StiRenderState renderState)
at Stimulsoft.Report.StiReport.Render(StiRenderState renderState, StiGuiMode guiMode)
at Socrates.Web.Reports.ReportService.Render()


Would appreciate any help ye could give me,
