Hi Indika,
maybe you can get something out of this code of mine. I can explain it
better later on when I have better time. BTW: hiiri is a mouse in
Finnish ;-)
cheers,
mika
map.events.register('click', null, function (e) {
OpenLayers.Util.getElement('nodelist').innerHTML = "Odota hetki...";
var hiiri = wfs.map.getLonLatFromPixel(e.xy);
var hiirixy = (hiiri.lat+','+hiiri.lon);
var url = wfs.getFullRequestString({
SERVICE: 'WFS',
