CustomItem not working on Nokia XpressMusic smartphone

[Vinicius Souza]

Im creating an aplication to Nokia XpressMusic smartphone. Ive created a CustomItem descendant called CommandButtom. Its worked perfectly on the emulator but not in the real thing.
To simplify my application, I created a class called Navigator that store all forms (2 forms now) and have methods like next(), previous() etc and its set automatically the Display to the corresponding Form. I dont know why, but since Im using this Navigator Class, the problem occurs. My CommandButtom is not correctly painted and display only a white rectangle.
Bellow my CommandButtom class to you guys see what Im doing wrong:

import javax.microedition.lcdui.CustomItem;
import javax.microedition.lcdui.Displayable;
import javax.microedition.lcdui.Font;
import javax.microedition.lcdui.Graphics;

public class CommandButtom extends CustomItem 
{
	public static final byte BT_SQUARE = 0;
	public static final byte BT_ROUND  = 1;
	public static final byte BT_CIRCLE = 2;
	
	private int tag;
	private int w, h;
	private byte type;
	private Displayable listener;
	private int buttonColor, fontColor;
	private boolean clicked;
	private String caption;
	
	public void setTag(int tag)
	{
		this.tag = tag;
	}
	public int getTag()
	{
		return (tag);
	}
	public String getCaption()
	{
		return caption;
	}
	public void setCaption(String caption)
	{
		this.caption = caption;
		repaint();
		
	}
	public void setType(byte t)
	{
		type = t;
	}
	public byte getType()
	{
		return type;
	}
    public CommandButtom(String label)
	{
		this(label, null, 40, 20);
	}
    public CommandButtom(String label, Displayable listener)
	{
		this(label, listener, 40, 20);
		tag = 0;
    }
    public CommandButtom(String label, Displayable listener, int w, int h)
	{
		super("");
		this.listener = listener;
		this.w = w;
		this.h = h;
		type   = BT_SQUARE;
		buttonColor  = 0xFFCC33;
		fontColor    = 0x000000;
		tag = 0;
		caption =  label;
		repaint();
    }
	
    protected int getMinContentHeight()
	{
		return h;
    }

    protected int getMinContentWidth()
	{
		return w;
    }

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

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

    protected void paint(Graphics g, int width, int height )
	{
		if (g == null) return;
		
        g.setColor(buttonColor);
		switch(type)
		{
			case BT_SQUARE:draw_square(g, width, height);break;
			case BT_CIRCLE:draw_circle(g, width, height);break;
			case BT_ROUND:draw_round(g, width, height);break;
		}
		g.setColor(fontColor);
		Font f = Font.getFont(Font.FACE_PROPORTIONAL, Font.STYLE_BOLD, Font.SIZE_SMALL);
		g.setFont(f);
	    g.drawString(caption, width / 2 + 1, height / 2 + 4, Graphics.HCENTER | Graphics.BASELINE);
    }
	
	private void draw_square(Graphics g, int width, int height)
	{
        g.fillRect(0, 0, width, height);
        g.setColor(255, 255, 255);
        g.drawRect(0, 0, width, height);
        g.setColor(127, 127, 127);
		if (!clicked)
		{
	        g.drawLine(0, height - 1, width, height - 1);
	        g.drawLine(width - 1, height - 1, width - 1, 0);
		}
		else
		{
	        g.drawLine(1, 1, width - 1, 1);
	        g.drawLine(1, 1, 1, height - 1);
		}
	}
	private void draw_round(Graphics g, int width, int height)
	{
        g.fillRect(0, 0, width, height);
        g.setColor(255, 255, 255);
        g.drawRect(0, 0, width, height);
 	}

	private void draw_circle(Graphics g, int width, int height)
	{
        g.fillArc(2, 2, width - 2, height - 2, 0, 360);
        g.setColor(255, 255, 255);
        g.drawArc(1, 1, width - 2, height - 2, 0, 360);
        g.setColor(127, 127, 127);
		if (!clicked)
	        g.drawArc(1, 1, width - 3, height - 3, 180 + 45, 180);
		else
	        g.drawArc(2, 2, width - 2, height - 2, 45, 45 + 135);
	}
	
	protected void pointerPressed(int x, int y)
	{
		clicked = true;
		((CommandButtomListener) listener).pointerPressed(x, y,  this);
		repaint();
	}

	protected void pointerReleased(int x, int y)
	{
		clicked = false;
		((CommandButtomListener) listener).pointerReleased(x, y, this);
		repaint();
	}

	protected void showNotify()
	{
		//repaint();
	}

Please, I need to know what is wrong.

Do you use the "setClip" method of Graphics class?

Do you first set the color before drawing each shape in the paint methods?
