Thanks for reply Guys! My business case is much more complicated. This was
just simple example.
I did like you said. It was interested that I had to start new thread to
process the loop.
Without it the label didn't refresh the counter value.
Here is my code, maybe it would be helpful for someone else:
this.counter = 100
final Label counterLabel = new Label("counter", new
PropertyModel(this,
"counter"));
counterLabel.add(new
AjaxSelfUpdatingTimerBehavior(Duration.seconds(3)) {
@Override
protected void onPostProcessTarget(AjaxRequestTarget
target) {
if (counter == 0) {
//close the window after countdown :)
window.close(target);
}
}
});
counterLabel.setOutputMarkupId(true);
add(counterLabel);
Form form = new Form("form");
add(form);
form.add(new IndicatingAjaxButton("confirmButton", form) {
@Override
protected void onSubmit(final AjaxRequestTarget target,
Form form) {
setEnabled(false);
setOutputMarkupId(true);
target.addComponent(this);
new Thread() {
public void run() {
for (int i = 0; i < 100; i++
) {
synchronized (this) {
//do business
here ;)
try {
wait(300); } catch (InterruptedException e) {
e.printStackTrace(); }
counter--;
}
}
}
}.start();
}
});
Btw, is is possible to add Behavior to the component in the
AjaxRequestTarget?
For exampel I want to add AjaxSelfUpdatingTimerBehavior but when the user
click on the button.
Thanks,
Artur
