[OpenLayers-Users] Some question to OpenLayers.Protocol.WFS.fromWMSLayer

[Kai Behncke]

Hi Marc,

thank you for that hint, but unfortunately it doesn` work (well, the pixel tolerance works but then the coordinate is not fitted and it gives an "empty"-WFS result).

I will try on.

Best regards, Kai
