THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!

class MyPage extends WebPage {
private String criteria;
//getter/setter for criteria
public MyPage() {
{panel}
IModel listModel=new LoadableDetachableModel() {
Object load() {
UserService service=...get user service;
List users=service.findUsersFiltered(criteria);
return users;
}
};
add(new ListView("users", listModel) {....});
{panel}

so here we have the listview that will show a list that is filtered on
page's criteria property. now we hookup our dropdownchoice in such a way
that it modifies this property and when the page refreshes so will the
listview because it is using a detachble model.

Form form=new Form();
add(form);
List filters=new ArrayList();
filters.add("a");
filters.add("b");
form.add(new DropDownChoice("filter", new PropertyModel(this, "criteria"),
filters) {
wantOnChangeNotifiactionwantOnChangeNotification() { return true; });
// here we glue dropdown choice to our criteria property via the property
model
}}
