Hey,
first of all I gotta say: a big thanks to you and your support, I got some
things fixed, I thought I'd never find the answer for :confused:
But unfortunately there's still the "Cannot reference this object. It
doesn't have an object number" error, when calling:
g2d.addLink(targetRect, tx, "0 0 595 842", PDFLink.INTERNAL);
What fop are you using?
Is that "SVG #svgView(viewBox())" bug-fix necessary, you mentioned earlier?
Thanks again Tim
