[iText-questions] The page 2 was requested but the document has only 1 pages.

Hi Paulo,

I'm attempting to create a PdfOutline to a PdfDestination to a target 
page after I have generated all the pages in the document. But the 
default initialization of PdfOutline is causing some problems.

The code sequence I use looks like this:

    PdfDestination dest = new PdfDestination(PdfDestination.FITBH, 300);
    PdfAction.gotoLocalPage(1, dest, writer);
    PdfOutline pdfOutline = new PdfOutline(root, dest, "label");
and the problem occurs (AFAICT) in PdfOutline.initOutline():

   void initOutline(PdfOutline parent, String title, boolean open) {
        ...
        setDestinationPage(writer.getCurrentPage());
   }
Since I'm creating the outlines after the last page is created, the call 
to writer.getCurrentPage() references a non-existing page.

I have attached a test program and a patch to PdfOutline that avoid the 
default call to setDestinationPage() when a destination is supplied 
already. At least it works for me, but maybe there is a better way?

regards,
finn
