I confirm. In one of the tickets I attached a screencast that shows that is seems pretty random https://www.dropbox.com/s/6elzwbwxcml1sck/postgis_editing_error.mp4 > Right now we are comparing the results ArcGIS is giving us against QGIS > topology checker.

I also would like to stress that this is a really serious issue. In QGIS we don't have (yet) tools to define the topology rules *before* starting digitizing as other software does (see the other thread on this matter). If the "avoid intersection" rule fails, we loose the basically the only weapon we have and vectors need to be cleaned with the "usual" tools (GRASS, postgis). _______________________________________________ Qgis-developer mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-developer
