Just found out that calling valid() for the components before returning does
the trick, but I guess that's not the correct approach. I added:
f.visitChildren(new IVisitor() {
public Object component(Component component) {
if(component instanceof FormComponent)
((FormComponent)component).valid();
return null;
}
});
in the onUpdate method of the AjaxFormComponentUpdatingBehavior, but it feels
kind of nasty :)

I created a standard quickstart project and added this to HomePage.java:
public class HomePage extends WebPage {
private ModelObject o = new ModelObject();
public HomePage(final PageParameters parameters) {
add(new FeedbackPanel("feedback"));
Form f = new Form("f", new CompoundPropertyModel(o));
add(f);
final TextField name = new TextField("name", Integer.class);
name.setRequired(true);
name.setOutputMarkupId(true);
f.add(name);
final TextField number = new TextField("number");
number.add(new AjaxFormComponentUpdatingBehavior("onblur") {
@Override protected void onUpdate(AjaxRequestTarget target) {
o.setName("Number " + number.getConvertedInput());
target.addComponent(name);
}
});
f.add(number);
f.add(new Button("submit"));
}
class ModelObject implements Serializable {
private Integer number;
private String name;
public Integer getNumber() {
return number;
}
public void setNumber(Integer number) {
this.number = number;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
}
And the HomePage.html:
<html xmlns:wicket="http://wicket.apache.org";>
<body>
<div wicket:id="feedback">Feedback</div>
<form wicket:id="f">
<fieldset>
<p>
<label>Number</label>
<input type="text" wicket:id="number" />
</p>
<p>
<label>Name</label>
<input type="text" wicket:id="name" />
</p>
</fieldset>
<input type="submit" wicket:id="submit" />
</form>
</body>
</html>
If you add a number and press tab, the name input will display "Name
<number>".
Works good until you try to submit once without a value in the name
input, and get the validation message "Field 'name' is required.".
After that, name will not be updated if you tab out of number.

Hi!
I have a form which uses a CompoundPropertyModel.
On the form I have a textfield which has a
AjaxFormComponentUpdatingBehavior connected to the onblur event. When
I have some data in the
field and tab out of the field, the onblur event will update some
other parts of the modelobject and add their respective components
(textfields) to the ajax target.
This works good until I once submit the form and get one or more
validation errors. After that, the changed data that occur in the onblur
event doesn't get pushed back with the ajax target. (They just
display their former data even though the model object was updated).
Can anyone think of what causes this, or should I create a testcase?
Sincerely,
Edvin Syse
