Is this okay? (I think i will add some explantion to it but i think this
exmaple explains it well):
class PersonList extends WebPage {
private List peopleList;
public PersonList(final List peopleList) {
this.peopleList = peopleList;
this.peopleList.add(new Person("Lila"));
this.peopleList.add(new Person("Bender"));
this.peopleList.add(new Person("Fry"));
add(new ListView("peopleList", this.peopleList) {
protected void populateItem(ListItem listItem) {
final Person person = (Person) listItem.getModelObject();
add(new Label("name", person.getName()));
add(new Link("editPerson") {
public void onClick() {
setResponsePage(new PersonEdit(person, peopleList));
}
});
}
});
add(new Link("newPerson") {
public void onClick() {
setResponsePage(new PersonEdit(new Person(), peopleList));
}
});
}
}
class PersonEdit extends WebPage {
private FeedbackPanel feedbackPanel;
private Person person;
private List peopleList;
public PersonEdit(Person person, List peopleList) {
feedbackPanel = new FeedbackPanel("feedbackPanel");
add(feedbackPanel);
add(new PersonForm("personForm", person, feedbackPanel));
}
class PersonForm extends Form {
public PersonForm(String s, Person person, IFeedback iFeedback) {
super(s, new CompoundPropertyModel(person), iFeedback);
add(new TextField("name"));
add(new Button("save"));
}
public void onSubmit() {
if (!peopleList.contains(person)) {
peopleList.add(person);
}
setResponsePage(new PersonList(peopleList));
}
}
}
class Person {
public Person() {
}
public Person(String name) {
this.name = name;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
private String name;
}

I think you missuderstood me or i was not able to explain it clear
enough.
I wanted to use the same Form/Page for Editing yet existing Persons
(which are in the People List) and edit new Persons (which has to be
added to the People-List).
Your solution does only work for editing new Persons but not for yet
existing ones. (Or maybe i just do not understand your solution
fully...)
But i found a solution for my Problem, and it goes like this:
On the Page where i show a list (Table) of Persons which are in the
People-List i have two links:
1. Edit link which does the Following:
onClick() {
setRepsonsePage(new PersonEdit(person, personList)); //person is a
reference to a existing Person Object
}
2. New Link which does the Following:
onClick() {
setResponsePage(new PersonEdit(new Person(), personList));
}
And on the PersonEdit Page it goes like this:
onSubmit() {
if (!this.personList.contains(this.person)) {
this.personList.add(this.person);
}
}
This works very well and i think it's clean and nice.
I think i will put it on the wicket wiki as a small tutorial, what
do you think?
Anyway thank you for your reply!

In your form:
public MyForm(String id, IModel model)
{
super(id, new CompoundPropertyModel(new Person()));
...
}
public void onSubmit()
{
Person newPerson = (Person)getModelObject(); // by now this
object is 'filled' using your form components
getPersonList().add(newPerson);
// now navigate to another page or set a new person to edit like
setModel(new CompoundPropertyModel(new Person()))
}

I have a Page with a Form to edit an Person object.
The Person object is always part of a People-List.
The Form uses a CompoundPropertyModel.
It works fine when i edit a given Person object.
So my question is now:
How can i implement it that the CompoudPropertyModel adds a new
Person object to the People-List when i use it for editinig a new
Person?
Thanks,
Dave
