Stela,
In that example you are querying layers Test1 and Test2.
Below you defined your control with layer _test
It is confusing...
You should try with a simpler example. I suggest you create a mapfile with 
one layer (don't forget the tolerance and template), create the wms layer 
in Openlayer and define the control on this layer only.

Re: [mapserver-users] Re: WMSGetFeatureInfo problem (No results, using OL)

Hi David!

The url is :

http://localhost/cgi-bin/mapserv.exe?map=map.map&&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetFeatureInfo&LAYERS=Test1,Test2&QUERY_LAYERS=Test1,Test2&STYLES=,&BBOX=-65.806807%2C-16.885911%2C-38.978193%2C-11.238939&FEATURE_COUNT=10&HEIGHT=257&WIDTH=1221&FORMAT=image%2Fpng&INFO_FORMAT=text%2Fhtml&SRS=EPSG%3A4326&X=366&Y=217

Executing that URL direct in browser generate that:

Content-type: application/vnd.ogc.se_xml 

Thanks

Stella

Stella, 

What does the getFeatureInfo call look like?  

Use Firebug to find the URL used to make the request and post it here.?

David.

WMSGetFeatureInfo  Javascript (OpenLayer)

var infoCtl = new OpenLayers.Control.WMSGetFeatureInfo({ 
                    layers: [_test], 
                    title: 'Click on the map to get information on 
layers', 
                    queryVisible: true, 
                    infoFormat: 'text/html' 
                }); 

                infoCtl.events.register("getfeatureinfo",map,showInfo); 

 function showInfo(evt) {    
            alert(evt.text);
} 

I´m getting that :

<html> 
  <head> 
    <title>MapServer Template Sample</title>
