I've got a pipeline which uses the Excel writer component to generate a workbook. The workbook opens and displays its data to the user when run in the Professional version of the PLP product. Some extra pilot script then runs on the workbook to retrieve chemical structures from the database using Accord Enterprise.

I'm now trying to replicate this behaviour where the pipeline is called from a web form where parameters are selected from drop down list boxes and passed to the pipeline. In both the professional edition and WebPort, I get a html report that there is no data and that there have been no errors and the workbook doesn't appear. What's strange is that if I replace the Excel writer component with a HTML table viewer, I get to see the data without problems.

Any ideas what is happening here and suggestions as to how I might get the parameter selection followed by the appearance of the workbook with structures with the user using WebPort?

Thanks.
