[Imran Rajjad]

Hi ,

my WMSGetFeatureInfo control is not returning any json,, my code is as below

basicControl = {
                   click : new OpenLayers.Control.WMSGetFeatureInfo({
	             url: 'http://10.0.80.41:7004/geoserver/wms',
	                title: 'Identify features by clicking',
	               layers: [network_wms],
	                queryVisible: true,
	                vendorParams: {
		 	            version: "1.1.1",
		 	            info_format: "text/plain",
		     		},
		 format : new OpenLayers.Format.GeoJSON()})             							};
                							
                							
                basicControl.click.events.register("getfeatureinfo",
this, showInfo);
                map.addControl(basicControl.click);

                function showInfo(evt) {
                	alert(evt); //
                  }
