Access a second java.util.List in a group?

[grinvon]

Hi there!

I am facing a new problem about iReport. I have a list with an entity model added. This entity have a list of another entity. The problem consists in how try to show the values from the second list.

Ex:

public class Company {

 private String name;

 private List<Person> people;

//getters and setters below...
}

public class Person {

 private String name;

//getters and setters below...
}

I need to show the person list values. I am using "JRBeanCollectionDataSource".

I had created a group and associated that list: "${files} is java.util.List". I noticed that I have one variable created in variables group as "grp_files_COUNT". I tried to use it to interact with that list, but a lot of erros pop up in the output console.

$F{files}.get($V{grp_files_COUNT}.intValue()).getName()

I really have no idea how to do it, some clues? Sorry about my poor english!

Regards!

You'll have to use a subreport or a list component to iterate the nested lists.  Groups are used for something else.
