Conversion problem moving from CS3 to CS4 - adding files to book

Question

I had a script which was working beautifully in CS3. Now we've moved to CS4 and it refuses to cooperate with me. I've tried a solution offered on the forum but it's not working for me.
        // Creating book
        var myBookFileName = myPath+"Personalized Modules/PW.indd";
         myBookFile = new File( myBookFileName );
        myBook = app.open( myBookFile );
         myBook = app.books.add( myBookFile );
        // Add the front cover
        myFilename = myPath+"Personalized Modules/PW_Cover.indd";
        myFile = File(myFilename);
        myBook.bookContents.add( myFile);
        // Add the rest of the individual files
For some reason, when it gets to the bookContents.add statement, it opens up a SaveAs dialog. I'm wondering if this is a setting within InDesign CS4 rather than a script issue.
I'd really appreciate any idea.

It looks like you're trying to add an existing CS3 document to a new CS4 book. InDesign wants to save the CS3 document in CS4 and so gives you the Save As dialog. You can either go through all the existing CS3 documents you'll be adding and save them out from CS4, or add a few lines to the script that will do it. (Change the variable name I used if it's used somewhere else in your script.)
// Creating book
var myBookFileName = myPath+"Personalized Modules/PW.indd";
myBookFile = new File( myBookFileName );
myBook = app.open( myBookFile );
myBook = app.books.add( myBookFile );
// Add the front cover
myFilename = myPath+"Personalized Modules/PW_Cover.indd";
myFile = File(myFilename);
// Save cover document in current version
myDoc = app.open(myFile,false);
myDoc.save(myFile)); // will overwrite CS3 file with CS4 file
myDoc.close();
myBook.bookContents.add(myFile);
// Add the rest of the individual files
I didn't test this code. Let me know if you have problems.
