<p dir="ltr">I''ve created the file in QGis, edited it in QGis, never used esri with this file. Id is the default field (i'm assuming this is the object id) QGis create when you create a shp. <br>

They are not really complex, nor numerous (25). I got id, DOSSIER, NOM_OPERAT, PRIORITE, COMMENTA, DATE_MAJ, SOURCE, LIBELLE_X, LIBELLE_Y fields and SURF_HA which is a virtual field.<br><br></div><div>Friday, it took me 5 min to save the file each time I modify a vertex.<br></div><div><br></div>Today, I update my id field with the expression "$id". Then, my shape file looks like a totally mess (look at the imgur album : <span><a href="http://imgur.com/a/noSM2" target="_blank">http://imgur.com/a/noSM2</a>). The LIBELLE_X, LIBELLE_Y fields have disappeard, the DOSSIER field which used to be null is now partially fulled, the NOM_OPERAT are truncated, fulled in a completelly non-sense manner. As for PRIORITE, DATE_MAJ. <br><br></span></div><span>Conclusion, 2 days of work in a trash.
