Is this techically possible?

[ehdtkqorl123]

I have a master report and a subreport.

A java file has a data source using a HashMap, and also has a parameter something like this:

 

<parameter name="SIMPLE_DATA" class="java.util.HashMap"/>

 

So subreport is used like this:

 

<subreportParameterExpression><![CDATA[$P{SIMPLE_DATA}.get($F{id})]]></subreportParameterExpression>

 

My question is.. is it possible for the master report to get the contents of the datasource(hashmap)?

I tried to dynamically set PrintWhenExpression properties based on the value of Datsource.

 

Can anyone help me? Thanks
