Multiple datasets, Exactly the same json (only one webservice call) - Extension and Another Example

Hy, and instead inject in a Table componant (jr:table),

it's possible to inject datas in a subReport ?

As exemple with Table and DataSetRun + DataSourceExpression (is working) :

                <jr:table>                    <datasetRun subDataset="Dataset1">                        <dataSourceExpression><![CDATA[((com.jaspersoft.webservice.data.query.IWSDataSource)$P{REPORT_DATA_SOURCE}).clone("results", $P{SubFieldsMap})]]></dataSourceExpression>

As wanted for call, a subreport for each node :

            <subreport>                <reportElement/>                <dataSourceExpression><![CDATA[((com.jaspersoft.webservice.data.query.IWSDataSource)$P{REPORT_DATA_SOURCE}).clone("@.results", $P{SubFieldsMap})]]></dataSourceExpression>                <subreportExpression><![CDATA["testsub_sub.jasper"]]></subreportExpression>            </subreport>

With a JSON like :

[{"id": 123,"result": [{   "symbol": "S_A_1"   },{   "symbol": "S_A_2"   }]},{"id": 456,"result": [{   "symbol": "S_B_1"   },{   "symbol": "S_B_2"   }]}]

For first subreport call, it will use array S_A_1, and S_A_2
For second subreport call, it will use array S_B_1, and S_B_2
