viernes, 23 de septiembre de 2005 � Problema con los par�metros en CR

Hi,

I�m trying to create a simple report with Crystal Reports in a JSP, using just one parameter. The report with the parameter is shown without problems but I get a �Some parameters are missing values� exception.

I�ve tried all the combinations that came to my mind without success. Have you faced this problem before ?

Any comment would be welcome !

Regards,

This is the JSP code I use to show the report (it�s a JSF tag)

<bocrv:reportPageViewer 
		viewerName="CrystalViewer" 
		parameterFields="#{testParams.params}"
		reportSource="#{reportWrapper.reportSource}"/>

This is the code to build the testParams.params field:

        ParameterFieldDiscreteValue pfieldDV1 = new ParameterFieldDiscreteValue();
        pfieldDV1.setValue("22");
        pfieldDV1.setDescription("Test description");

        Values vals1 = new Values();
        vals1.add(pfieldDV1);

        ParameterField pfield1 = new ParameterField();
        pfield1.setReportName("");
        pfield1.setName("testParam");
        pfield1.setCurrentValues(vals1);
        pfield1.setDescription("Test description");

        Fields fields = new Fields();
        fields.add(pfield1);
		
        return fields;

And the exception I get:
