Hi all.
Short and simple code with a strange mistake in it or not. I hope you
can help me.
I am writing something ;) in J2ME. It?s a canvas class which will be
used in a midlet.
At the end of this message you can see the error message.
There is something with the keyReleased methode. Without the methode
it?s running fine.
I know you will only see a huhu in console and not in display, but it
should run without an error.
Thanks for your help.

Regards,
Marcel

public class DigiPairCanvas extends Canvas {

        private Graphics graphics;
        
        public DigiPairCanvas(Display display) {
        }
        
        public void keyReleased(int keyCode) {
                if (keyCode == KEY_NUM0) System.out.println("huhu");
        }
        
        protected void paint(Graphics graphics) {
        }
}
