GoogleMaps cluster di markers non riesce

[supermac]

FORUM SBAGLIATO, SPOSTATEMI PLEASE GRAZIE

Non capisco, non riesco a fare i cluster di markers: continuo ad ottenere un milione di markers singoli e nella consolle di errore vedo marker.getPosition is not a function.
Se posto un po' di codice qualcuno mi illumina?
Here it is:

    var mymap;
    var mapExists = !!document.getElementById("nomemappa");
    var allMyMarkers = [];
   
    var stylem = [
        {stili mappa }
    ]

    var customLabel = {
        P: {
            label: '',
            icon: '/Google%20Maps%20Markers/orange_MarkerP.png'
        },
        S: {
            label: '',
            icon: '/Google%20Maps%20Markers/blue_MarkerS.png'
        }
    };



    function initMap() {
        if (mapExists) {
            mymap = new google.maps.Map(document.getElementById('macmap'), {
                center: new google.maps.LatLng(latitudine, longitudine),
                zoom: 12,
                styles: stylem 
            });
            
            var bounds = new google.maps.LatLngBounds();
            var infoWindow = new google.maps.InfoWindow;

            //hfQS > ashx > xml
            downloadUrl(document.getElementById("hfQS").innerText, function (data) {
                var xml = data.responseXML;
                var markers = xml.documentElement.getElementsByTagName('marker');

                // Add a marker clusterer to manage the markers in locations array.
                var markerCluster = new MarkerClusterer(mymap, markers, { imagePath: '/Google%20Maps%20Markers' });
       
                Array.prototype.forEach.call(markers, function (markerElem) {
                    var name = markerElem.getAttribute('name');

                    var point = new google.maps.LatLng(
                        parseFloat(markerElem.getAttribute('lat')),
                        parseFloat(markerElem.getAttribute('lng')));
                    bounds.extend(point);
                    
                    var infowincontent = document.createElement('div');
                    var strong = document.createElement('h3');
                    strong.textContent = name;
                    infowincontent.appendChild(strong);
              
                    var myicon = customLabel[type] || {};

                    var marker = new google.maps.Marker({
                        map: mymap,
                        position: point,
                        label: myicon.label,
                        icon: myicon.icon
                    });
                                        
                    markerCluster.addMarker(marker, false);

                    allMyMarkers.push(marker);
                        
                    marker.addListener('click', function () {
                        infoWindow.setContent(infowincontent);
                        infoWindow.open(mymap, marker);
                    });

                }); //fine for

                mymap.fitBounds(bounds);

            });

            // Override map zoom level once our fitBounds function runs 
            var boundsListener = google.maps.event.addListener((mymap), 'bounds_changed', function (event) {
                this.setZoom(14);
                google.maps.event.removeListener(boundsListener);
            });
        }
    }


    function downloadUrl(url, callback) {
        var request = window.ActiveXObject ?
            new ActiveXObject('Microsoft.XMLHTTP') :
            new XMLHttpRequest;

        request.onreadystatechange = function () {
            if (request.readyState == 4) {
                request.onreadystatechange = doNothing;
                callback(request, request.status);
            }
        };

        request.open('GET', url, true);
        request.send(null);

up, grazie

Visto che ho anche un array di markers ho provato anche a usare il metodo addMarkers(allMyMarkers,true) dopo il mymap.fitbounds ma con lo stesso risultato... sempre getPosition is not a function :-(

...
  //markerCluster.addMarker(marker, false);

                    marker.addListener('click', function () {
                        infoWindow.setContent(infowincontent);
                        infoWindow.open(mymap, marker);
                    });

                    //locations.push(point);
                    allMyMarkers.push(marker);
                }); //fine array
                mymap.fitBounds(bounds);

                // Add a marker clusterer to manage the markers in locations array.
                var markerCluster = new MarkerClusterer(mymap, markers, { imagePath: '/Google%20Maps%20Markers' });
                markerCluster.addMarkers(allMyMarkers, true);

            });

Esperti di mappe, aiuto!!!

ma che pistola!
