Passing parameter to subdataset

[ethael]

Hello everybody,

 

I have a master report with 4 subreports. Last of the subreports has 4 charts. So that 4th subreport has 4 subdatasets. I am passing parameters from master to all subreports. But I don't know how to pass parameter from subreport to subdataset.

I have tried to declare parameter that is comming from master in subreport and then put this parameter into datasetRun of the subdataset:

<datasetParameter  name="classpath">
       <datasetParameterExpression><![CDATA[$P{classpath}]]></datasetParameterExpression>
</datasetParameter>

parameter classpath comes from master reports. I have declared this parameter in subreport too:

    <parameter name="classpath" isForPrompting="false" class="java.lang.String">
    </parameter>

but the exception is that there is unkown parameter classpath in subdataset.

 

can anyone help?

I have solved the problem. I just forgot to put parameter declaration also to subdataset tag.
