How to prevent creation of new scriptlet

[pmaslov]

Hi, we are having problem with migrating from jasperreports 3.0 to 3.6.
The problem occurs in reports where we are using a custom scriptlet which is initialized with a parameter. The instance of the scriptlet is created outside of Jasperreports and passed as REPORT_SCRIPTLET parameter when report is filled.
The report has a cosstab inside which uses a custom data source. It seems that the Jasperreports 3.6 framework is creating a new instance of the scriptlet for that data source. As oppose to version 3.0 which was reusing the instance that was passed as REPORT_SCRIPTLET parameter. The new scriptlet instance is created by framework (using default contructor) and does not work properly.
Is there a way to prevent creating of scriptlet instances by framework?

That's a bug, log it using the project trackers.

A workaround is to explicitly pass a scriptlet instance to the crosstab dataset, see below.

Code:

<crosstabDataset>	<dataset>		<datasetRun subDataset="..">			<datasetParameter name="REPORT_SCRIPTLET">				<datasetParameterExpression><![CDATA[new net.sf.jasperreports.engine.JRDefaultScriptlet()]]></datasetParameterExpression>			</datasetParameter>		</datasetRun>	</dataset></crosstabDataset>
