Hi ! I dont think that it is the problem, because WMSGetFeatureInfo is generating the "correct" url (I think)...
Anyway I tested querying only 1 single layer and got the same result... Dammit :( Thanks anyway Stella On Wed, Jan 27, 2010 at 12:24 PM, Eichner, Andreas - SID-NLKM < [email protected]> wrote: > > Hi Stella, > > according to > http://dev.openlayers.org/docs/files/OpenLayers/Control/WMSGetFeatureInfo-js.htmlthe > WMSGetFeatureInfo control's constructor takes an array of > OpenLayers.Layer.WMS objects.
