[Users] Problems with WMSGetFeatureInfo-Popup

[IT Intern]

Funny, it only works for me if I use both:
 location: new
OpenLayers.LonLat(mapPanel.map.getLonLatFromPixel(event.xy)).transform(new
OpenLayers.Projection("EPSG:4326"), new
OpenLayers.Projection("EPSG:900913")),
 lonlat: mapPanel.map.getLonLatFromPixel(event.xy),
