Hi all,

i`ve got 2 Problems with my GMap. Im using Java Server Faces and
Richfaces, my map is displayed in xhtml-file. Everything works fine,
the markermanager too, except the funcition clearMarkers() does not
remove all of my markers. Would be nice if someone can have a look at
my code.
Second Problem - can i delete a map and re-initialize it? I`d like to
display 2 maps on one page, or recreate a complete new map on the
first ones position. When i do so, my browser is loading my xhtml-file
endlessly. When i abort hte loading of the page and press F5 i got the
correct display.

Thanks a lot & lg schlumsch

Regarding your first problem:

The normal way to use MarkerManager is to have *one* MarkerManager
instance to which you add lots of markers. If you do it that way, then
you can write

function clearMarkers() {
  mgr.clearMarkers();

What your code does is create lots of MarkerManager instances, each of
which handle one marker. Your "mgr" variable is a reference to the last
MarkerManager that you created, so you can only make calls that affect
the marker that that MarkerManager manages.

Well, i`m sorry but i dont have the possibility to link my code now.
So i have to post some code again.

When i define gmarkers and mgr global, no marker is shown on the map,
error: map2 is not defined.
When i define both in a function, for example in createpoints, no
error is produced but also no marker shown :)

 var mgr = new MarkerManager(map2);

                var markerlist = [];

                function createPoints(data) {

                                                        for (var i = 0; data.length; i++) {
                                                        var point = new GLatLng(data[i].latitude, data[i].longitude);
                                                        map2.setCenter(point);
                                                        map2.setZoom(16);
                                                        map2.addOverlay(createMarkerWithIdentifier(point, data[i].id,
data[i].beschreibung));

                                                }
                                                mgr.addMarkers(markerlist);
                                                mgr.refresh;
                                        }

                                        function createMarkerWithIdentifier(point, id, beschreibung) {

                              var nummer = id;
                      var idIcon = new GIcon(baseIcon);
                      idIcon.image = "http://www.schlumsch.eu/e2e/
gmapicons/marker" + id + ".png";
                      markerOptions = { icon:idIcon };
                                          var marker = new GMarker(point, markerOptions);
                                          GEvent.addListener(marker, "click", function() {
                                            marker.openInfoWindowHtml(beschreibung);
                                          });
                                          GEvent.addListener(marker, "dblclick", function()
{ mgr.removeMarker(marker); } );
                                                markerlist.push(marker);

                                          return marker;
                                        }

Please follow the posting guidelines and give a link to your map page.

So, can anybody tell me how to modify the above given code (sorry
again)? Even when i create lots of markermanagers like in my first
posting, the delete-link is not working. (should kill the last one) O
only the listener for doubleklick works fine...

thx & lg schlumsch
