[Qgis-user] [QGis 2.10]Error while saving shape file

[Mats Elfström]

Hi Pierre!
Your Id field, which you updated, is it the FID or Object ID field in the
shapefile?
If so, you have broken the shape file by updating it outside of ESRI
applications.
The FID is the internal key between the geometry and the dbase attribute
table, and it should never be altered or trusted, or used for any purpose.
Actually, QGis ought to hide that field by default.

Regards, Mats.E
