the request being made is not really a problem
BTW but that conditional statement doesn't work here, event.feature.length
is equal to 0 but nothing is being showed, chrome console shows that
everything works on wms request, ie the response is correctly sent to the
browser.
the problem is that event.features.length is always 0
code:
var info = new OpenLayers.Control.WMSGetFeatureInfo({
url: 'wmsserver',
title: 'Identify features by clicking',
queryVisible: true,
eventListeners: {
getfeatureinfo: function(event) {
var l = event.features.length;
alert(event.features.length+"-"+l)
if( event.features.length > 0 )
{
map.addPopup(new OpenLayers.Popup.FramedCloud(
"sostegno",
map.getLonLatFromPixel(event.xy),
null,
event.text,
null,
true
));
}
}
}
});
