NullPointerException with Infinite Progress Dialog

[Tim Gaul]

Hi

I'm experiencing an issue with the InfiniteProgressDialog and my animated image.

Theme constant:

infiniteImage=loading.gif (this is a 4 frame gif of about 160x160 pixels)

My code:

    {
      showInfiniteProgressDialog();
      ... do something
      hideInfiniteProgressDialog()
    }

    public static void showInfiniteProgressDialog() {
        InfiniteProgress ip = new InfiniteProgress();
        infiniteProgressDialog = ip.showInifiniteBlocking();
    }
   
    public static void hideInfiniteProgressDialog() {
        infiniteProgressDialog.dispose();
    }

And my error:

java.lang.NullPointerException
    at com.codename1.impl.javase.JavaSEPort.getRGB(JavaSEPort.java:3037)

Thanks!

Hi,
you should use a regular image not an animated GIF for images in the infinite progress.
We can't rotate a GIF.

Thanks Shai.

Will do that for now; and look at replacing the infiniteprogress with a custom component at a later stage, when I have more time.
