Issue with af:tree

Question

The af:tree element always tries to display a node as if it has children, even if its child List is of size 0. The result is that all nodes appear as expandable folders and when you expand on a node that has no children you get a vertical line leading to nothing. Clearly this isn’t desirable. This behavior is seen even when using your packaged sample code as shown below:
public class Person
public Person(String name)
_name = name;
public String getName()
return _name;
public List getKids()
return _kids;
private final String _name;
private final List _kids = new ArrayList();
You can construct a tree by:
Person john = new Person("John Smith");
Person kim = new Person("Kim Smith");
Person tom = new Person("Tom Smith");
Person ira = new Person("Ira Wickrememsinghe");
Person mallika = new Person("Mallika Wickremesinghe");
john.getKids().add(kim);
john.getKids().add(tom);
ira.getKids().add(mallika);
List people = new ArrayList();
people.add(john);
people.add(ira);
Now you can construct a TreeModel by:
TreeModel model = new ChildPropertyTreeModel(people, "kids");
