I have a report, this report with several subreports, sometimes throws an error when loading "Could not load report", but however still loads the report. (not my current issue, just as some additional information)
I clicked on a subreport, and an exception was thrown "The communication channel has not been created."
Stacktrace is:
CrystalDecisions.ReportAppServer.Controllers.DatabaseControllerClass.ReplaceConnection(Object oldConnection, Object newConnection, Object parameterFields, Object crDBOptionUseDefault) at CrystalDecisions.CrystalReports.Engine.Table.ApplyLogOnInfo(TableLogOnInfo logonInfo)
This is on my dev machine with local SQL Server running, everything is working fine otherwise.
