If I first delete the 0,000000 default value, then enter my param, it works fine. This is a general issue with Processing, and I believe it's a true bug of Processing (user inputs should never be discarded without consent). BTW, what is the meaning of the `lower` polygon? All the best, and thanks again. -- Paolo Cavallini - www.faunalia.eu QGIS & PostGIS courses: http://www.faunalia.eu/training.html https://www.google.com/trends/explore?date=all&geo=IT&q=qgis,arcgis _______________________________________________ Qgis-developer mailing list [email protected] List info: http://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: http://lists.osgeo.org/mailman/listinfo/qgis-developer
