Problem Filling and Selecting with Paths.jsx

Question

I have copied Paths.jsx from the Adobe Photoshop CS5 Javascript Scripting Reference, p. 141.  It works OK.  It makes a path that is the outline of an ice cream cone and strokes it with the current foreground color.
I then tried to fill the path and that does not work.  I have tried 3 methods using the following additional code and changing the appropriate false's to true:
// Fill the path
fillColor = new SolidColor
fillColor.rgb.red = 255
fillColor.rgb.green = 0
fillColor.rgb.blue = 0
try {
   if(false) {
         // This works and gives a gray fill that is neither the
              // foreground nor background color
     // Only the ice cream part of the cone is selected and filled
            myPathItem.fillPath()
   } else if(false) {
     // With a color specified, it doesn't work
              myPathItem.fillPath(fillColor)
       } else if(true) {
     // This makes a selection of the PathItem, selects it and fills it
     // Only the ice cream part of the cone is selected and filled
              myPathItem.makeSelection(0, false, SelectionType.REPLACE)
               selRef = app.activeDocument.selection;
              selRef.fill(fillColor, ColorBlendMode.NORMAL)
} catch(ex) {
        msg = "Error filling path:\n" + ex.message
        alert(msg, "Exception", true);
They do as the comments say.  None of them does what I would expect.  For the second way, the error message is:
General Photoshop error occurred.  This functionality may not be available in this version of Photoshop
- Could not complete the command because of a program error.
I do not understand why only the      ice cream part of the cone is filled or selected (the third array).  I can manually      make a selection from the Path in PS and it also only selects the      ice cream part.  All of the lines are stroked.  Only the top part is      filled or selected.
Why does fillPath not work?
I can supply the whole script if necessary.  I am an experienced programmer but new to Photoshop scripting.  Is this a bug or am I doing something wrong?
Thanks for any help.

This is the whole script:
