I use Quantum GIS 1.8.0 on Windows 7 Professional, 64 bit. I have problem with WFS Layer. I tried tree WFS:
1) Download services - Parcels (Czech Republic) http://services.cuzk.cz/wfs/inspire-cp-wfs.asp?service=WFS&request=GetCapabilities
Example #3 is OK.
Example #2 shows Error "The layer geoportal.cuzk.cz/WFS_GN/WFService.aspx?SID=27082012_03561414729376000_PM_021892838861&SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&TYPENAME=gmgml:GEONAMES&SRSNAME=EPSG:102067 is not a valid layer and can not be added to the map"
Example #1 shows Error "capabilities document contained no layers."
I don't know, where are the differences between services. Could you help me?
