Hi,
maybe someone has an idea!?!

--------------------------------------------------
public class test extends Canvas {

int paintCount = -1; // because setCurrent(canvas) calls paint() too

public void run() {
try {
Display.getDisplay(this.midlet).setCurrent(this);
repaint();
repaint();
serviceRepaints();
if (paintCount == 0) System.out.println("error");
}

public void paint(Graphics g) {
paintCount++;
System.out.println(paintCount);
}
}
--------------------------------------------------

the result is:
0
error
1

The method paint() is only executed ones for two calls of repaint(). So far so good. Printing the paintCount indicate that paint() did run. Now, why does serviceRepaints() not wait until the paint() method has finished ???
Im running this in simulation with WTK2.0.
 
It is sorta covered in the JavaRanch Style Guide.
