Hi Victor, Sorry for the late reply. Thanks for the fix. Now for the second case described in my question, it works well. The results are correct as per the explanation by Bernhard.
Now for the first case, the results are not correct. Please see the before and after results from a simple shapefile. There are two issues. First, the left and right half circles are not created in the result. The polygons are not splitting among each other as can be seen from the color differences in the result. Note - this is probably due to the iterator getting closed when issuing a getFeaturebyId request..although I am not sure.. Do you want me to file a ticked for this? <http://osgeo-org.1560.x6.nabble.com/file/n5052152/results.png> Thanks Vinayan -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Union-Tool-Ftools-Sextante-How-should-the-real-result-be-tp5051653p5052152.html Sent from the Quantum GIS - User mailing list archive at Nabble.com. _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
