Hi Totò,<br>
as you already know, QGIS handles ESRI File Geodatabase layer via the <br>
GDAL/OGR library.<br>
The GDAL/OGR library has two different drivers for the ESRI File <br>
Geodatabase forma: the built-int driver "OpenFileGDB" [1] (which is <br>
available on all systems) and the "FileGDB" driver (available on Windows <br>
through OSGeo4W) which depends on the ESRI FileGDB API SDK [2].<br>
Using which driver does the issue occurs?<br>
<br>
How do you update the data?<br>
<br>
I think you should inform the GDAL/OGR developers about the issue. Since <br>
you experience the issue often, it shouldn't be so difficult to provide <br>
a sample ESRI File Geodatabase layer and exact steps in order to <br>
replicate the issue.<br>
<br>
Best regards.<br>
<br>
Andrea Giudiceandrea<br>
