Hi,
Create a panel that has a child an image (the busy indicator).
Add a timer behavior to this panel and check whether the slow operation is
done and replace the image with another component that renders the new data:
public void onTimer(AjaxRequestTarget target) {
Data newData = getNewData();
if (newData != null)
{
NewComponent c = new Component(image.getId(), newData);
image.replaceWith(c);
target.add(c);
}
else {
// target.appendJavaScript("still waiting ...");
}
}
