Script engine error: Report parameter "HomeFolder" does not exist.

Hi, I'm getting an error when generating a report with BIRT Runtime. I set the value of the Home Folder Property Binding to params["HomeFolder"] and then tried to generate the report using the following commands.

C:\>%BIRT_HOME%\ReportEngine\genReport -f PDF -p HomeFolder=C:\FlatFiles c:\BIRTReports\BMFInvoice.rptdesign

C:\>%BIRT_HOME%\ReportEngine\genReport -f PDF -p "HomeFolder=C:\FlatFiles" c:\BIRTReports\BMFInvoice.rptdesign

C:\>%BIRT_HOME%\ReportEngine\genReport -f PDF -p "HomeFolder"="C:\FlatFiles" c:\BIRTReports\BMFInvoice.rptdesign

All of them resulted in the following error:

Oct 28, 2010 2:31:44 PM org.eclipse.birt.report.engine.data.dte.AbstractDataEngine prepare
SEVERE: Error evaluating Javascript expression. Script engine error: Report parameter "HomeFolder" does not exist.
Script source: <inline>, line: 0, text: params["HomeFolder"]

Any assistance would be appreciated.

Thanks,
Jason

Here's an image of the parameter value.

From http://digiassn.blogspot.com/2006/09/birt-passing-parameters-from-command.html I found that -p "PARAMETER=VALUE" is the correct format. So that's not the issue.

There isn't a parameter called "HomeFolder" defined in your report. I went ahead and modified it, added the parameter, and modified the script to check if it is null before it uses the value of the passed in parameter. That should take care of your issue.
