I forgot to include the HomePage.html. Here is all the files of my small
test. Please check it out if possible. If you run it with JS off, all is
fine. With JS on, Ajax response is wrong.
HomePage.html:
<html>
<head></head>
<span wicket:id="message">message will be here</span>
<form wicket:id="form">
<input type="text" wicket:id="word"/>
<input type="submit" value="Enter" wicket:id="submitButton"/>
</form>
<span wicket:id="feedback">FEEDBACK</span>
</html>
HomePage.java:
public class HomePage extends WebPage {
private static final long serialVersionUID = 1L;
private String word;
public HomePage(final PageParameters parameters) {
add(new FeedbackPanel("feedback") {
private static final long serialVersionUID = 1L;
@Override protected void onBeforeRender() {
System.out.println("= = = = FeedbackPanel
onBeforeRender()");
System.out.println(" FeedbackbackMessageModel = "
+ getFeedbackMessagesModel().getObject());
super.onBeforeRender();
}
}.setOutputMarkupPlaceholderTag(true));
// if the word "blowup" is entered,
//this register a error message and throw
IModel model = new Model() {
private static final long serialVersionUID = 1L;
@Override public Object getObject() {
if (word != null && word.equals("blowup")) {
word = "-w-e-b-l-e-w-u-p-";
HomePage.this.fatal("[2/2]This message is from Model.");
getPage().detach();
System.out.println("! ! ! ! ! throwing new
AbstractRestartResponseException()");
throw new AbstractRestartResponseException() {
private static final long serialVersionUID = 1L;
};
} else {
return "The word is: \"" + (word == null ? " n u l l " :
word) + "\"";
}
}
};
add(new Label("message", model) {

@Override protected void onBeforeRender() {
System.out.println("= = = = Label onBeforeRender(), model =

super.onBeforeRender();

add(form);
form.add(new TextField("word").setRequired(true));
