Passing the List of primitive type objects as datasource for subreport

Question

I need to pass to my subreport a dataSource with help of master report\'s List parameter. I don\'t know what is

Answer 1

Yes it works. It's totally not clearly documented but it works with jasperreport 4.5.1.

You have to declare a field into your subreport named "_THIS", typed with your primitive type you want to display. In this case, a String.

SubReport

    
        
    
    
    
  ...

Then in this subreport where you want to display the String value, just use $F{_THIS}.

Main report

The parent report provide the List as the datasourceExpression
