My assumption that you were taking about a hidden text field was wrong. There was a bug in old versions that caused NullPointerExceptions when manipulating OC groups in existing PDFs. Maybe that bug is causing your problem; maybe not. I'm not sure if OCGs can be merged when concatenating documents.
