JRC thick client dynamic parameter issue

Question

Hello,
I am creating a thick client report viewer using CR for Java (v 12) to accompany our Java database client app and I am having trouble with reports that have parameter lists that should populate with database data when a rpt file is opened.
For example, our users create groups of records in an Oracle database.  The report, upon opening, should prompt the user to select a group to use with the report.  The prompt appears, but the list of available group name values is empty.  The report populates the list as expected in both the XI and 2008 designer software, but no dice when the rpt file is opened via the ReportViewerBean.  If the group name is manually typed in, the report runs, so the replaceConnection seems to be working.
I have looked through all of the examples, but I can't find one that addresses database-populated parameter lists specifically for a thick-client app.  Any help would be appreciated!
Thanks.

Hi Ted,
Yes, I'm using the latest CR4E and it's the web viewer.
I've got more information from the report designer in how the dynamic lists were created in case there is something in there that hints at why it isn't working in our case. The reports are created in Crystal Reports 2008.
From Field Explorer select New Param, under list of values select Dynamic. In Value column select the field name. Set Allow Multiple values to true.
Then under the Select Expert choose Record. Select the field to link. Choose is Equal to and then choose the parameter created above.
In code I'm not doing anything related to these lists.
ReportClientDocument clientDoc = new ReportClientDocument();
clientDoc.setReportAppServer("inproc:jrc");
clientDoc.open(fullPath, OpenReportOptions.openAsReadOnly.value());
CRJavaHelper.replaceDBConnection(clientDoc, username,
                         password, dbConnectionUrl, driverClassName, "",
                         schema);
clientDoc.save();
CRJavaHelper.addDiscreteParameterValue(clientDoc, "",
          producedByNameKey, producedByName);
CRJavaHelper.addDiscreteParameterValue(clientDoc, "",
          logoKey, reportLogoUrl);
reportSource = clientDoc.getReportSource();
CrystalReportViewer crystalReportPageViewer = new CrystalReportViewer();
crystalReportPageViewer.setReportSource(reportSource);
crystalReportPageViewer.setOwnPage(true);
crystalReportPageViewer.processHttpRequest(req, resp,
               getServletContext(), null);
Is there anything to be done in code to get it to work?
