URLImage and Label's Background image

[GoogleCodeExporter]

Tested on Simulator (Skin iPhone & Nexus).
Tested on 5S.
Not using the new VM or the new Graphics Pipeline.

What steps will reproduce the problem?
1. Create a new CN1 project.
2. In the state machine class, in the protected void postMain(final Form f) 
method, add the code as below.

Image imu = URLImage.createToStorage(
    encodedPlaceHolder, 
    "bgjpg", URL, 
    URLImage.RESIZE_SCALE
);
f.setLayout(new LayeredLayout());

Label l = new Label("");
l.getUnselectedStyle().setBgColor(0xFF0000);
l.getUnselectedStyle().setBgImage(imu);
l.getUnselectedStyle().setBackgroundType(Style.BACKGROUND_IMAGE_SCALED_FIT);
l.getUnselectedStyle().setBgTransparency(255);
l.setSelectedStyle(l.getUnselectedStyle());
f.addComponent(l);

With encodedPlaceHolder your placeholder and URL the url of the picture you 
want to display.

What is the expected output? What do you see instead?
I expect to see, inside my red label the downloaded picture in its background.
I just see my red label without a background picture.

What version of the product are you using? On what operating system?

I can provide our Netbeans Project if easier. I haven't yet since the zip file 
is more than 20Mb.

At the time when you load the image, its data won't we loaded yet.  You need to 
poll the image, and refresh the label once it is received.

if ( imu.isAnimation() && imu.getImageData() == null ){
   // set timer to poll.....
}

// And inside the timer's run

if ( imu.animate() ){
      // repaint the label, or the form, or anything that uses the image
      // and turn off the timer.
}

Note, you'll want your image to be at least an EncodedImage (not an Image) so 
that you have access to the getImageData() method.
