Martin,
The problem is here:
add(new TestForm("testForm", new Model(person)));
You are creating a Model, when in fact you should be creating a
CompoundPropertyModel.
Components that do not have models ( ie your RequiredTextField ) only
"inherit" models that are of type CompoundPropertyModel or derivatives there
of.
To fix your example try
add(new TestForm("testForm", new CompoundPropertyModel(person)));
See the model wiki page for more explanations on models.

Subject: [Wicket-user] Newbie problem with Model-s
Hi,
I have problems with updating models with data from page, I can't uderstand
why it dosn't work :( Can anybody tell me what I'am doing wrong ?
There is my very simple sample.
package wicket.examples.my;
import java.io.Serializable;
import wicket.markup.html.WebPage;
import wicket.markup.html.form.Form;
import wicket.markup.html.form.RequiredTextField;
import wicket.model.IModel;
import wicket.model.Model;
import wicket.model.PropertyModel;
public class TestFieldPage extends WebPage {
class Person implements Serializable {
private String name = "TEST";
public void setName(String name) {
this.name = name;
}
public String getName() {
return name;
}
}
public TestFieldPage() {
Person person = new Person();
add(new TestForm("testForm", new Model(person)));
}
class TestForm extends Form {
public TestForm(String id, IModel model) {
super(id, model, null);
add(new RequiredTextField("name", new PropertyModel(
model, "name")));
}
public void onFormSubmitted() {
System.out.println(((Person) getModelObject()).getName());
}
}
}
with this markup:
<?xml version="1.0" encoding="UTF-8"?>
<html xmlns="http://www.w3.org/1999/xhtml";>
<head>
<title>My Wicket Example</title>
</head>
<body>
<form wicket:id="testForm">
Name: <input type="text" wicket:id="name"/> </form> </body> </html>
