That is because you did override a method, Form.onFormSubmitted, that
was not meant for that. We try to shield you from this kind of errors as
much as possible with Wicket, but sometimes that is not possible. In
this case we couldn't make onFormSubmitted not final as we needed to
override this in UploadForm, and maybe more. That's why we put fat
warnings with method comments if they are not meant for direct use and/
or overriding. This one:
/**
* THIS METHOD IS NOT PART OF THE WICKET API. DO NOT ATTEMPT TO
OVERRIDE OR
* CALL IT.
*
* Handles form submissions. By default, this method simply calls
validate()
* to validate the form and update the model if there is only one
button. If
* there is more than one button, it calls the onClick() method for the
* button which submitted the form.
*
* @see Form#validate()
*/
public void onFormSubmitted()
{
So... to fix your problem, use onSubmit instead:
class TestForm extends Form {
public TestForm(String id, IModel model) {
super(id, model, null);
add(new RequiredTextField("name", new PropertyModel(
model, "name")));
}
public void onSubmit() {
System.out.println(((Person) getModelObject()).getName());
}
}
Furthermore, I didn't see a submit button, so you'll need to put that in
as well:
<?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"/>
<input type="submit" value="save" />
</form>
</body>
</html>
Good luck,
Eelco

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>
