Jasper CVC Component with Sub-Dataset

Question

I'm working on CVC component in Jasper Studio. It is working fine with the "ReportMainDataset" but when I'm using the "Sub Dataset" it is not plotting.

Just wanted to know does CVC component works with "Sub Dataset" or not. If works, guide me how can I achieve this.

Answer 1

The tag for indicating the dataset is <cvData>

Example

subdataset

<subDataset name="Dataset1" uuid="03d50d7f-1b96-486a-ac64-7d2c6e440433">
    <queryString>
        <![CDATA[select count(*) t, shipcountry, shipcity from orders group by shipcountry, shipcity order by shipcountry, shipcity]]>
    </queryString>
    <field name="SHIPCOUNTRY" class="java.lang.String"/>
    <field name="T" class="java.lang.Long"/>
    <field name="SHIPCITY" class="java.lang.String"/>
</subDataset>

component

<cvc:customvisualization xmlns:cvc="http://www.jaspersoft.com/cvcomponent" xsi:schemaLocation="http://www.jaspersoft.com/cvcomponent http://www.jaspersoft.com/cvcomponent/component.xsd" evaluationTime="Report" onErrorType="Icon">
  <cvc:itemProperty name="script" value="d3_zoomable_circle_packing.min.js"/>
  <cvc:itemProperty name="css" value="d3_zoomable_circle_packing.css"/>
  <cvc:cvData>
    <dataset>
        <datasetRun subDataset="Dataset1" uuid="bd23d50f-2149-4985-a0ac-883505172688">
            <parametersMapExpression><![CDATA[$P{REPORT_PARAMETERS_MAP}]]></parametersMapExpression>
            <connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]></connectionExpression>
        </datasetRun>
    </dataset>
    <cvc:item>
        <cvc:itemProperty name="category">
            <valueExpression><![CDATA[$F{SHIPCOUNTRY}]]></valueExpression>
        </cvc:itemProperty>
        <cvc:itemProperty name="subcategory">
            <valueExpression><![CDATA[$F{SHIPCITY}]]></valueExpression>
        </cvc:itemProperty>
        <cvc:itemProperty name="value">
            <valueExpression><![CDATA[$F{T}]]></valueExpression>
        </cvc:itemProperty>
    </cvc:item>
  </cvc:cvData>
</cvc:customvisualization>

EDIT: As @dada67 comment it does not seem to work properly, I have also test it with sample d3_zoomable_cricle_packing.jrxml without success, this is the bug issue

The work around, create a subreport!
