gabrielbondor Posted August 28, 2013 Share Posted August 28, 2013 i have a jasper .jrxml template file and a parameter defined like this <parameter name="relativesList" class="java.util.List"/>. i would like to use this parameter as a datasource for a list, but it doesn't work. The list is always empty. This is how i set the datasource.<dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.data.JRMapCollectionDataSource($P{relativesList})]]></dataSourceExpression>And this is how i define the dataset.<subDataset name="relativeDataSet" uuid="de1b6afc-f2db-4568-af5d-56f0287976b3"><parameter name="bullet" class="java.lang.String"/><field name="relativeEntry" class="java.util.HashMap"><fieldDescription><![CDATA[_THIS]]></fieldDescription></field> Please tell me why the list is always empty. The parameter passed to the document i'm sure that is not empty.Thank you! Link to comment Share on other sites More sharing options...
