I wonder how I rerender an Image using the AjaxSelfUpdatingTimerBehavior?
I've created an image like:
Image image = new Image("imgId", new DynamicImageResource() {
@Override
protected byte[] getImageData() {
// Get the byte data
}
});
image.add(new AjaxSelfUpdatingTimerBehavior(Duration.seconds(30)));
image.setOutputMarkupId(true);
The ajax debug window says that a request is sent every 30th second but the
getImageData() is never called again. I've probably misunderstood something
here, so could someone please enlighten me on how this could be achieved?
Thanks
