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);
// create the list of root nodes:
List people = new ArrayList();
people.add(john);
people.add(ira);
Now you can construct a TreeModel by:
TreeModel model = new ChildPropertyTreeModel(people, "kids");
the constructor calls:
-setWrappedData(...); (with people)
-setChildProperty(...); (with "kids")
setWrappedData() is overridden from javax.faces.model.DataModel;
with getWrappedData(); you get acces to the List of people.
So... what you want it to "update" the used model;
(remove/add objects from/to the list)
and you can use these methods to sync the data, represented by the
(childproperty)treemodel.
