Hi Christos (!),
sorry but your code works only in QGis 1.8 version. I am using the 2.0.1 version and pyQGis methods are changed: http://hub.qgis.org/wiki/quantum-gis/Python_plugin_API_changes_from_18_to_20 BTW, my problem is: - using a SHP file layer, elements are returned - using SpatiaLite layer, elements are returned, but each is empty. It 'a known issue? Someone in the list has tried it?
