Default Private variables assignment

Please Login to Remove!


I have a very strange behavior of my application at 8800 blackberry device.

For some strange reason I could not assign a value to private int class members. At device simulator it works OK.

Can someone take a look and help me?

Thank you,

Here is a simplified code:
class PenDemo extends UiApplication
private PenDemoScreen _screen;

// constructors and so on

// inner class
private class InputThread extends Thread
public void run()
XYPoint[] buffer;
// ......

for (;;)
penPoint = new XYPoint(buffer[2], buffer[3]);
xyPoint = new XYPoint();

// in TransformToXY I'm using classes from
// other project in my JDE, but I deploy it into
// devise
TransformToXY(penPoint, xyPoint);

// addPoint will lead to problem
// statement
_screen.addPoint(xyPoint.x, xyPoint.y);
_screen.invalidate(xyPoint.x, xyPoint.y, 1, 1);

class PenDemoScreen extends MainScreen
private DrawArea _drawArea;

public void addPoint(int x, int y)
_drawArea.addPoint(x, y);
// .........
class DrawArea extends BitmapField
private int _newX;
private int _newY;
private boolean _pointAdded;

public void addPoint(int x, int y)
// here is a problem.
// when I trace this code in simylator, I could see
// correct assignment and _newX and _newY obtains
// there new values.
// at device _newX and _newY has some values and they
// could not been changed they are the same during app
// execution and when I run app next time they could
// have another values.
// The very strange thing that _pointAdded could be
// changed.
this._newX = x;
this._newY = y;
this._pointAdded = true;


public void paint(Graphics graphics)
graphics.drawLine(10, 10, 234, 568);

graphics.drawPoint(this._newX, this._newY);
this._pointAdded = false;
