Hi!
Tnx Igor, I finally got it working after quite some wrestling.. I
understood I must extend the AjaxButton? I shall play around with it
some more in order to more fully understand it.
However, in case someone else needs it too, my complete code and
markup is available below for ajax busy indicator for form submit
button.
/**
* This class TODO
*/
public class IndicatorLogin extends WebPage {
private static final long serialVersionUID = 1L;
/**
* Constructor for TODO
*/
@SuppressWarnings("serial")
public IndicatorLogin() {
final Form loginForm = new Form("loginForm", new Model());
final AjaxIndicatorContainer indicatorContainer = new
AjaxIndicatorContainer(loginForm);
{
TextField userIdField = new TextField("userId", new Model());
userIdField.setRequired(true);
loginForm.add(userIdField);
}
{
PasswordTextField passwdField = new
PasswordTextField("password", new Model());
passwdField.setResetPassword(false);
loginForm.add(passwdField);
}
{
final AjaxButton loginButton = new MyAjaxButton("loginButton",
loginForm) {
@Override
protected void onSubmit(AjaxRequestTarget arg0, Form arg1) {
simulateLoginTransaction();
}
public String getAjaxIndicatorMarkupId() {
return indicatorContainer.getMarkupId();
}
};
loginForm.add(loginButton);
}
add(new FeedbackPanel("feedback"));
add(loginForm);
}
/**
* This method TODO
*/
synchronized void simulateLoginTransaction() {
System.out.println("Transaction begin.");
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("Transaction complete.");
}
}
/**

@SuppressWarnings("serial")
class AjaxIndicatorContainer extends WebMarkupContainer {
/**
* Constructor for TODO
* @param form
*/
public AjaxIndicatorContainer(Form form) {
super("ajaxIndicator"); // wicket:id
setOutputMarkupId(true);
setMarkupId("ajaxIndicatorId"); // markup:id
form.add(this);
}
/**

*/
@Override
protected void onComponentTag(ComponentTag tag) {
super.onComponentTag(tag);
tag.put("src",urlFor(AbstractDefaultAjaxBehavior.INDICATOR));
}
}
abstract class MyAjaxButton extends AjaxButton implements IAjaxIndicatorAware {
/**
* Constructor for TODO
*
* @param id
* @param form
*/
public MyAjaxButton(String id, Form form) {
super(id, form);
}
};
