Hie, I had a problem with a biblio framework where field corresponding to biblionumber was visible (090$9) : In this case, editing a record and saving it made a record with 2 fields 090. It comes from the fact that this field is always added by Biblio->TransformHtmlToMarc(), meaning it shouldn't be visible. It does work when this field is hidden in framework. I also noticed that this field is set again by Biblio->_koha_marc_update_bib_ids(). Is it a bug ? -- Fridolyn SOMERS Information and Communication Technologies engineer fridolyn.somers@gmail.com
