[OpenLayers-Users] tooltipPopup feature

[tvnc]

using measure control each time when i click to paritial measure distance, 
point feature is added to vector layer. i call tooltipPopup function on 
mouseover the feature. but it wan't draw a popup, giving me some kind of 
event.feature problem

  markers = new OpenLayers.Layer.Vector("Markers"); 
				  map.addLayers([markers]);
				  
					var bot = new OpenLayers.Control.Button
({
    				displayClass: 'olIkonaUdalj',
    				eventListeners: {
				  	'activate': klikLivo,
				  	'deactivate': brisMarkera}, 
				  	type: 2
					});
					
				
					var kontr = new OpenLayers.Control.Panel
({
					 div: document.getElementById("bp"),
				    //defaultControl: bot
				  	});  
				kontr.addControls([bot]); 	
            map.addControl(kontr);	 
            
            function klikLivo(event) {
       		
       		/*
				if(markers.features.length==0) return;   
				var i = markers.features.length - 1;
				tocke.push(markers.features
[i].geometry);        
            var lineString = new OpenLayers.Geometry.LineString(tocke);
            var lineFeature = new OpenLayers.Feature.Vector(lineString);
 
   		 poli.addFeatures([lineFeature]);
           */
        		pn.deactivate();
           var crta = new OpenLayers.Control.Measure(OpenLayers.Handler.Path, 
{persist: true});

                    "measure": handleMeasurements,
                    "measurepartial": handleMeasurements
                });

                crta.activate();
