Hi,

I just installed Gmap and acquired my API key. Before adding the key i could see the map. After adding the key, the map under node locations and build a macro are grey/empty. The map under User locations, however, comes up just fine.

I've seen some people post about this but have not seen any conclusive answers/fixes.

Sorry I cannot help out here ... I'm not a developer.

Any ideas would be much appreciated!

I'm not sure if this is right, but check the API key you probably entered for the Location module. It's under admin/settings/location/geocoding; choose Configure Parameters to edit the key. The API for both modules probably needs to match for things to work right.

Thanks. I had entered the key in both places at the same time. So I think we can rule that one out.

Just discovered a new clue ... It seems that when there are locations associated with a specific map the grey shows up, but when it cannot find any locations to plot, it does show the map.

For instance, when i deleted the two nodes that contained location data, the Node Locations map worked again. And when I added my user location to my account settings, the User Locations map stopped working.

So...if data exists for a map, it displays grey. No data, it works.

Hmmmm......

Well, it looks like I figured it out and may have uncovered a bug. Under Marker Manager (In the GMap Config admin/settings/gmap) I had originally selected "GMarker Manager" just because I always assume adding Google to the mix can't be a bad thing. After I changed it back to "No manager (use addOverlay directly)" the grey map issue went away. Not sure how to use the Marker Manager but it is either not working or I am not aware of other files/requirements to get the Google GMarker Manager working.

Assuming there are no other requirements to get this working, I believe this to be a bug.

yes, I have the same problem here.
without a marker manager, the map shows up fine, with marker manager the map is just grey and firebug shows me javascript errors:

Drupal.gmap.marker has no properties (.../modules/gmap/js/gmarkermanager_marker.js Line 12)
a.q() has no properties (http://maps.google.com/mapfiles/maps2.69.api.js Line 1055)

when using "Google's GMarkerManager"
and

Drupal.gmap.marker has no properties (.../modules/gmap/js/clusterer_marker.js Line 12)
Clusterer is not defined (.../modules/gmap/js/clusterer_marker.js Line 9)

when using "Jef Poskanzer's Clusterer"
as Marker manager

Small status update:

using the very latest version from cvs, I now at least see a map when using "Jef Poskanzer's Clusterer", but I still get the 2 javascript errors, I don't see the map-navigation controls and (you guessed it) no markers either.
using "Google's GMarkerManager" still results in a gray map.

Neither clusterer or gmarkermanager are currently working. It's been on my todo list like forever...

Constructor of GMarkerManager should be called only after call to map.setCenter function, i assume it is because GMarkerManager can't setup viewport correctly. If you will not call map.setCenter before initialization of GMarkerManager, you will get grey map.

Do not works:
map = new GMap2(document.getElementById("map"));
mgr = new GMarkerManager(map);

map.setCenter(new GLatLng(55.73948, 10.67871), 9);

Works:
map = new GMap2(document.getElementById("map"));
map.setCenter(new GLatLng(55.73948, 10.67871), 9);

mgr = new GMarkerManager(map);
