Enter event field color change issue

Question

I'm trying to make a script that will change the color of a field's content area when the user enters it (either through clicking or tabbing to the field). It seems simple enough to do, but I haven't been able to get it working.
I downloaded the sample .pdf file that describes how to do this at: http://partners.adobe.com/public/developer/en/livecycle/designer/pdfs/FieldFillColor.pdf
Push the button, the colors change. Seems to work fine, right? Except for the horrible, horrible period in the color definition, of course. Publishing a 2 line script with a bug as an EXAMPLE? For shame.
But, when you move the code to the Enter event, the caption changes color, but the content area does not... until you LEAVE the text box, at which point it DOES change color. This doesn't make any sense to me. Is there something undocumented going on here that I don't know about, or is this just another bug?

This won't speed it up, but I suggest making your code a lot cleaner by making use of this class (I haven't tested it):
public class ColorRange {
   private Color min, max;
   public ColorRange(Color min, Color max) {
      this.min = min; this.max = max;
   public boolean contains(Color c) {
      return c.getGreen() >= min.getGreen() && c.getGreen() <= max.getGreen() &&
         c.getRed() >= min.getRed() && c.getRed() <= max.getRed() &&
         c.getBlue() >= min.getBlue() && c.getBlue() <= max.getBlue();
//...SNIP...
ColorRange blue, red, green, yellow; //initialize these
//...SNIP...
   if ( blue.contains(robot.getPixelColor(640,480) ) {Furthermore, I would introduce constants for your sample locations:
Point blueLoc = new Point(640, 480); //etcEdited by: endasil on 14-Sep-2009 10:21 AM
