pageToOpen for opening PDF not working

Hi there

I’m trying to create a looping function that will open each page in a multi-page PDF, do some things, then save and close the document. However, the pageToOpen property of the PDFFileOptions object seems to be having no effect—I am prompted to select a page each time.

Here is my code so far:

var fileRef = File.openDialog('Please select the file to be imported:');

var pdfOptions = app.preferences.PDFFileOptions;

pdfOptions.pDFCropToBox = PDFBoxType.PDFBOUNDINGBOX;

for(i = 0; i < 10; i++){

    pdfOptions.pageToOpen = i + 1;

    if (fileRef != null) {

        var myDoc = open(fileRef, DocumentColorSpace.RGB);

    }

}

I’m using Illustrator CS4 on Windows 7.

I’d appreciate any insights.
