I'm new to ZK and being Italian, I can't fully understand documentation. Readed all way long through that but still not found a proper solution. I encounter this problem: I have a model called StatisticGroup, each of them has a property called operators, containing a collection of Operator(s). For clarity, a StatisticGroup can have many Operator(s) and an Operator belongs to a StatisticGroup. I need to show these Operator(s) in a <grid> element, with their StatisticGroup as a <group> element. I saw a nested template example in docs but didn't understand it.

How can i display these data (Operators) within a nested template?

StatisticGroup model

public class StatisticGroup implements Serializable
{
  private long id;
  private long name;
  private List<Operator> operators;
  // Omitted getters and setters.
}

Operator model

public class Operator implements Serializable 
{
  private long id;
  private string firstName;
  private string lastName;
  // Omitted getters and setters.
}

*Controller *

public class ControllerOperators extends SelectorComposer<Component>
{
  @Wire
  private Grid grid;

  public ArrayList<StatisticGroup> StatisticGroups;

  @Listen("onCreate = #grid")
  public void creaGriglia()
  {
    this.StatisticGroups = fetchStatisticGroupFromDB();
    tabella.setModel(new ListModelList<StatisticGroup>(StatisticGroups));
  }
}

* ZUL page *

<grid id="grid">
  <columns sizable="true">
    <column label="Last Name"/>
    <column label="First Name"/>
  </columns>
  <rows>
    <template name="model">
      <group label="${each.name}"/> // The StatisticGroup name.
        <template name="model">
          <row>
            <label value="I have to show Last Name for each operator"/>
            <label value="I have to show First Name for each operator"/>
          </row>
    </template>
    </template>
  </rows>
</grid>

There are some runnable examples at GitHub. You can download the whole project and run it which will express more clearly than texts.
