SVGImage and viewPort: image is not displayed in phon (fine in emulator)

[thehappycoder]

I am trying to display a svg image scaled to the width of the display. It is displayed fine in emulator but not in the phone (nokia 5800) -- I see just a white box. If I remove a 'viewBox' attribute, the image gets displayed but not scaled to the width.

Image:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG Tiny 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11-tiny-flat.dtd">
<svg xmlns:svg="http://www.w3.org/2000/svg"
    xmlns="http://www.w3.org/2000/svg"
    version="1.1"
    baseProfile="tiny"
    width="200" height="200" viewBox="0 0 200 200">

    <g stroke="#EEDA72" stroke-width="2" transform="translate(100 100)" >
        <circle id="outerCircle" r="95" fill="#E59816" stroke-width="3" />
        <circle id="innerCircle" r="80" fill="#FFFCA0" />

        <line id="hourHand" x1="0" y1="0" x2="0" y2="0" stroke="black" />
        <line id="partsHand" x1="0" y1="0" x2="0" y2="0" stroke="black" />
    </g>
</svg>

And the CustomItem:

    public SVGImageItem(String label, InputStream inputStream, ExternalResourceHandler externalResHandler) {
        super(label);

        try {
            this.scalableGraphics = ScalableGraphics.createInstance();
            this.image = (SVGImage) SVGImage.createImage(inputStream, externalResHandler);
            this.animator = SVGAnimator.createAnimator(image);
            this.animator.setTimeIncrement(0.01F);
            this.animator.play();
            this.canvas = (Canvas) animator.getTargetComponent();
        } catch (IOException e) {
            throw new RuntimeException("Caused by " + e.getClass() + ": " + e.getMessage() + "\n"

        }
    }

    public SVGAnimator getAnimator() {
        return animator;
    }

    public void updateAnimation(Runnable runnable, boolean invokedNow) {
        try {
            if (invokedNow) {
                animator.invokeAndWait(runnable);
            } else {
                animator.invokeLater(runnable);
            }
        } catch (InterruptedException ex) {
            ex.printStackTrace();
            // XXX find out what to do;
            // throw new RuntimeException("Interrupted!");
        }

        repaint();
    }

    public SVGImage getImage() {
        return image;
    }


    protected int getMinContentWidth() {
        return 0;
    }

    protected int getMinContentHeight() {
        return 0;
    }

    protected int getPrefContentWidth(int height) {
        return height;
    }

    protected int getPrefContentHeight(int width) {
        return width;
    }

    protected void paint(Graphics g, int w, int h) {
        this.scalableGraphics.bindTarget(g);
        this.image.setViewportHeight(h);
        this.image.setViewportWidth(w);

        this.scalableGraphics.render(0, 0, this.image);
        this.scalableGraphics.releaseTarget();
    }

}

If you need to see more code, I will give you a link to the git-repository.

I found the problem (see commented out line). But I don't know why it happens. Any ideas?

private void updateTime() {
        this.slavicTime = SlavicDateUtil.convert(new Date());

        timeItem.setLabel(slavicTime.getHourName());
        timeItem.setText(slavicTime.getHours() + " : " + slavicTime.getParts());

        clockFace.update(slavicTime, true);
    }

    private void init() {
        ...
        clockFace = new ClockFace(null, clockFaceInputStream, null);
        clockFace.setLayout(Item.LAYOUT_NEWLINE_AFTER);
        clockFace.setPreferredSize(mainForm.getWidth(), mainForm.getWidth());
        mainForm.append(clockFace);

        // No blank (with white background) image if this is commented
        // updateTime();
        resumeTimer();
    }

    private void resumeTimer() {
        timer = new Timer();
        timer.schedule(new TimerTask() {
            public void run() {
                System.out.println("Update time!");
                updateTime();
            }
        }, 0L, 1000L);
    }

...
ClockFace.java:

    protected void paint(Graphics g, int w, int h) {
        this.scalableGraphics.bindTarget(g);
        this.image.setViewportHeight(h);
        this.image.setViewportWidth(w);

        this.scalableGraphics.render(0, 0, this.image);
        this.scalableGraphics.releaseTarget();
    }
