Hi Marvin,

first I have to say that from your description I didn't fully get what =
you would like to achieve and which result you get.=20

The PDFMergerUtility already appends the outline of your children as a =
child to the outline of your parent. That's why you get it twice.

=46rom the source:


	PDDocumentOutline destOutline =3D =
destCatalog.getDocumentOutline();
        PDDocumentOutline srcOutline =3D =
srcCatalog.getDocumentOutline();
        if( srcOutline !=3D null )
        {
            if( destOutline =3D=3D null )
            {
                PDDocumentOutline cloned =3D
                    new PDDocumentOutline( =
(COSDictionary)cloner.cloneForNewDocument( srcOutline ) );
                destCatalog.setDocumentOutline( cloned );
            }
            else
            {
                PDOutlineItem first =3D srcOutline.getFirstChild();
                if(first !=3D null)
                {
                    PDOutlineItem clonedFirst =3D new PDOutlineItem(
                            (COSDictionary)cloner.cloneForNewDocument( =
first ));
                    destOutline.appendChild( clonedFirst );
                }
            }
        }
