[JS OSX problem executing CS3 script in CS4 ]

Question

I created a program in CS3 for hyperlink. Following code will work fine in CS3. But when i am trying to run this program in CS4 its not giving me any error but i am not getting  expected output.
var myTextFrame_np = mydoc.pages.item(i).textFrames.add();
myTextFrame_np.geometricBounds = ["38p0", "26p0", "40p0", "30p0"];
var source_np = mydoc.hyperlinkPageItemSources.add(myTextFrame_np,{name:'P1:P2'});
var dest_np = mydoc.hyperlinkExternalPageDestinations.add();
dest_np.documentPath = myfile;
dest_np.destinationPageIndex = 2;
dest_np.viewSetting = HyperlinkDestinationPageSetting.fitWindow;
mydoc.hyperlinks.add(source_np, dest_np, {visible:false, name:'P1:P2'});
Can anyone tell me what i need to change in this program to work in CS4.
Thank you,

I created a test case for you. Copy the code into ESTK and run for CS4. I am sending Amit.indd file as well in your mail box please check the attachment. You can check now what is the problem. 
var file_path = "/Users/amitvyawahare/Desktop/Amit.indd";
var OpenDocument = app.open(File(file_path));
myDoc = app.activeDocument;
var myfile = File(file_path);
var nextPage = ["38p5", "26p0", "40p0", "30p0"];  // Next Page text frame for hyperlink (y1, x1, y2, x2)
var prevPage = ["38p5", "21p0", "40p0", "25p0"];  // Previous Page text frame for hyperlink (y1, x1, y2, x2)
var myNextFrame = myDoc.pages.item(0).textFrames.add();
myNextFrame.geometricBounds = [nextPage[0], nextPage[1], nextPage[2], nextPage[3]]; 
var myNextSource = myDoc.hyperlinkPageItemSources.add(myNextFrame,{name:'P1:P2'});
var myNextDest = myDoc.hyperlinkExternalPageDestinations.add();
myNextDest.documentPath = myfile;
myNextDest.destinationPageIndex = 2;
myNextDest.viewSetting = HyperlinkDestinationPageSetting.fitWindow;
myDoc.hyperlinks.add(myNextSource, myNextDest, {visible:false, name:'P1:P2'});
When you finish execution try to open the showDestination it wount work.
But  when you open P1:P2 hyperlink or try to open hyperlink option which is under hyperlinks.
Then try to open showDestination that time it will work.
