Crystal Reports For Eclipse - Multi-values not showing on page..

Tried two different ways to set params, but to no avail. Values seems to be set, but only one value appears on the report.The value is updated, so not an old value or anything.

Also if I look at the values I can see the values are set! The Field is set to multi=true and the height is big enough to display lots of date grow=true.

ReportClientDocument clientDoc = (ReportClientDocument) session.getAttribute(reportName);

if (clientDoc == null) {

// Report can be opened from the relative location specified in the CRConfig.xml, or the report location

Object[] multiVals = {theValue1, theValue2};

// sReportName - the report that contains the specified parameter field.

ParameterField paramField = new ParameterField();





Fields parameterFields = new Fields();




// Show parameter values to console

Fields fields = viewer.getParameterFields();

for (int i = 0; i < fields.size(); i++) {

ParameterField pf = (ParameterField)fields.get(i);

Values v = pf.getCurrentValues();

if (v.isEmpty()) {


} else {

System.out.println("v.size(): " + v.size());

for (int j = 0; j < v.size(); j++) {

ParameterFieldDiscreteValue pfdv = (ParameterFieldDiscreteValue)v.get(j);

System.out.println(pf.getName() + " - " + pfdv.getValue());




// Apply the viewer preference attributes


// Process the report

viewer.processHttpRequest(request, response, application, null);

Thanks in advance!

Not too good the SAP support in this forum. Maybe ditch it and use JasperReports...
