[OpenLayers-Users] Reload marker

[Walter Lorenzetti]

Hi list,

I've a problem with a reloading of several markers layers

On my application I've n markers layer where I add severla 
OpenLayers.Marker by parsing a featureserver gml output (I hope you 
understand...)

like this:

for (var tp in legDbTipo){
  punti[tp] = new OpenLayers.Layer.Markers(tp);
}



function parseData(req) {
          g =  new OpenLayers.Format.GML();
          features = g.read(req.responseText);
          for(var feat in features) {
            // si crea la feature

            var f = new OpenLayers.Feature(base, new 
OpenLayers.LonLat(features[feat].geometry.x,features[feat].geometry.y));
              f.attributes = new Object;
              for (var j in features[feat].attributes) {
                  f.data[j] = features[feat].attributes[j];
                  f.attributes[j] = features[feat].attributes[j];
              }
              f.closeBox = true;
              f.popupClass = AutoSizeFramedCloudMinSize;
              f.data.popupContentHTML = bulidFormpopup(f,true);
              f.data.overflow = "auto"
              var size = new 
OpenLayers.Size(legDbTipo[f.data.tipo].dimLegMapIcon.w,legDbTipo[f.data.tipo].dimLegMapIcon.h);
              f.data.icon = new 
OpenLayers.Icon(legDbTipo[f.data.tipo].urlLegMapIcon,size);
              OpenLayers.Console.log(f);
            // si crea il marker
            var m = f.createMarker();
        
            m.events.register("mousedown", f, markerClick);
           
            var markerClick = function (evt) {
                if (this.popup == null) {
                    this.popup = this.createPopup(this.closeBox);
                    map.addPopup(this.popup);
                    this.popup.show();
                } else {
                    this.popup.toggle();
                }
                currentPopup = this.popup;
                OpenLayers.Event.stop(evt);
            };
            punti[f.data.tipo].addMarker(m);
          }
        }


function load_punti(){
  OpenLayers.loadURL("/fs/featureserver.cgi/punti_turistici?format=GML", 
"", null, parseData);
}

If I want to refresh my data I write this function:

function destroy_punti(){
  for (var tp in legDbTipo){
    for(var m in punti[tp].markers){
      punti[tp].markers[m].destroy();
    }
  }
}

so with this I destroy every markers before created....

and after running load_punti() again I repopulate my markers layers...

but after that I've a problem with every action on the map because on 
firebug I obtain the segunt error:

this.events is null
this.events=new 
OpenLayers.Events(this,t...this.icon!=null)){this.icon.moveTo(px);}

Someone have an idea about this error?

Thanks in advance

Walter
