Export Report to PDF after user has entered parameters

Question

Hi All,
I have a problem exporting a report to PDF using "ReportExportControl" after a user has entered parameters, instead of showing the download prompt, it displays the report using the parameters as if it was using "CrystalReportViewer"
If I program the input fields using "ParameterFieldController" then the exporter works as expected.
Is there anything in particular needed in order to export a report with user inputted parameters?
Thanks in advance.
Michael

Hi Ted, thanks for your reply,
What I am seeing at the moment is as follows
The report requires parameters from the user in order to generate the report, and a webpage asking the user to inputs is shown, the same one that is shown by "CrystalReportViewer" function, once the user has inputted the parameters they click the "OK" button and the report generates on screen, using the parameters entered, behaving like "CrystalReportViewer" function, what I need is once the user click "OK" it will prompt for download as attachment, which is not happening.
For your suggestion, I already have that coded and its still not working, Please find my code attached
// Create a exporter object
ReportExportControl exportControl = new ReportExportControl();
exportControl.setReportSource(clientDoc.getReportSource());
// Exporter Options
ExportOptions exportOptions = new ExportOptions();
exportControl.setExportOptions(exportOptions);
exportControl.setExportAsAttachment(true);
exportOptions.setExportFormatType(ReportExportFormat.PDF);
// Process the http request to export the report
exportControl.processHttpRequest(request, response, getServletConfig().getServletContext(), null);
// Dispose of the exporter object
exportControl.dispose();
with the above code the report will display on screen, but if i include this before the code
//Use the ParameterFieldController to pass parameter values to the report
ParameterFieldController paramController;
paramController = clientDoc.getDataDefController().getParameterFieldController();
paramController.setCurrentValue("", "Parameter name", Val);
the report doesnt show the input screen and generates as attachment
Hope this makes my situation abit clearer
Thanks and regards
Michael
