NullPointerException forever! Weird problem..

Question

Note: I'm using Motorola SDK for Motorola OS Products Version 6.4
this is my MIDLET classs
protected void startApp() throws MIDletStateChangeException
          this.myList = new ListCanvas(Font.SIZE_SMALL, false);
          this.myList.setTitle("asdsd");
          display.setCurrent(this.myList);
     }and this is my Canvas derived class
import javax.microedition.lcdui.Canvas;
import javax.microedition.lcdui.Graphics;
public class ListCanvas extends Canvas
     private String title;
     public ListCanvas(int FontSize, boolean textCentreAligned)
          this.title = "";     
     protected void paint(Graphics grfx)
          grfx.setColor(0x00FFFFFF);          // White Bg
          grfx.fillRect(0, 0, this.getWidth(), getHeight());
          grfx.setColor(0x000000);
          grfx.drawString(this.title, this.getWidth() / 2, 0, Graphics.HCENTER | Graphics.TOP);
     public void setTitle(String text)
          System.err.println(text);
          this.title = text;
}its quite simple.. all its doing is drawing some text on the screen...
now when im running it using the emulator in the SDK..
i get
1. "null" printed in debug window << from the System.err.println() in setTitle()
2. java.lang.NullPointerException occurred in ListCanvas.paint(Graphics), ignored.
the basic problem here is no matter what i do.. i don't know why the string im passing to my canvas class is going through as a null??
therefore i cant use it in the drawstring...
it always keeps giving me this exception..
the same problem also appears on cell phone which runs Motorola OS so its not an only desktop emulator problem!
though it works perfectly on WTK and Motorola for Linux OS products emulator!! and other cell phones...
whats the solution to this please?? im really tired and need this work

It's weird no doubt, but have you tried initializing title at declaration?String title = "zzz";Other things you can try: rename methods, rename parameters, rename variables, rename classes.
All of which suggestions no doubt sound absurd, but some years ago I faced a security violation (the dreaded Windows C000..005) in a Visual FoxPro program, and was 100% sure that my code was OK. The problem went away after I renamed a report file. Then I've had blackout crashes of Microsoft&reg; HTML Help editor -- no error message, the program window simply disappeared every time I tried to compile a particular help file -- which was solved by renaming a MIDI file from popcorn.mid to pop.mid... which was used in ALL my other help files, which compiled fine with the original name.
When you're clutching at straws, and the fault is not yours, you have to try everything!
Wish you luck, Darryl
