I've created a map and I allow users to search for a location. I
think allow them to look for markers within a particular distance of
this location. The map zooms to an appropriate level to show all
these markers.
When you click on any of the markers an infowindow opens and shows
some details.
Users can then search for a new location and then see markers within a
particular distance again etc.
After clicking, zooming and pulling up new locations I get an
intermittent problem of
TypeError: Error #1009: Cannot access a property or method of a null
object reference.
at com.google.maps.core::MapImpl/closeInfoWindow()
at com.google.maps.core::MapImpl/openInfoWindow()
at com.google.maps.overlays::Marker/openInfoWindow()
at com.google.maps.wrappers::IMarkerWrapper/openInfoWindow()
My create marker code is
public function createMarkermap(currentLocation:Object, number:int,
type:String):void {
var opts:MarkerOptions = new MarkerOptions({
strokeStyle: new StrokeStyle({color: 0x987654}),
fillStyle: new FillStyle({color: 0x3399FF, alpha: 0.8}),
radius: 12,
hasShadow: true
});
opts.label = String(number);
var marker:Marker = new Marker(new
LatLng(currentLocation.latitude, currentLocation.longitude),opts);
marker.addEventListener(MapMouseEvent.CLICK,
function(e:Event):void {
marker.openInfoWindow(new InfoWindowOptions({contentHTML:
"<b>" + "MAP" + "</b><br/>" + currentLocation.shorttitle + "</b><br/>"
+ Math.round(currentLocation.distance) + " " + type + " from current
location"}));
});
map.addOverlay(marker);
}
Whenever I look for a new location or new markers I clear all overlays
and start again passing new marker objects to the createmarkermap
function. I've no idea why i get this problem. However I have a
sneaking feeling it's something to do with the zoom. It happens more
often after the map has changed it's zoom.
Any ideas ??
