CR2008 - "The system cannot find the path specified"

Hi,

I have a report designed with CR 2008.

In my VB.Net programm I execute a "CrystalDecisions.CrystalReports.Engine.ReportDocument.Export" to export the report f.ex. to pdf.

This works fine.

Now I add a incorrect formula to the report with {TSQLTable.TField_ThatDoesNotExist} = "Otto".

When I export the report I receive now "The system cannot find the path specified" which does not reflect the real problem.

When showing the report with the incorrect formula in the Viewer, I get the correct error message

This Field name is not known

Details: errorKind

Error in file....

So why doesn't the export show the correct error message?

Thanks

Patrick
