Error adding marker to the marker manager

[Nathan Raley]

Okay, I am having a bit of a problem moving from v2 to v3.  I've narrowed down the error to adding a marker to the marker manager.

I am storing markers that are using coordinates from user values into an array StartFinishMarkers[].

I create my MarkerManager via:

ZoneStartFinishMM = new MarkerManager(map);

I create the Markers via:

StartMarkerOptions = { "icon": StartPoint, "clickable": true, "draggable": true, "title": Number };

FinishMarkerOptions = { "icon": FinishPoint, "clickable": true, "draggable": true, "title": Number };

var StartMarker = new google.maps.Marker(point1, StartMarkerOptions);

var FinishMarker = new google.maps.Marker(point2, FinishMarkerOptions);

Now I have my Marker Manager and Markers created, I used try catches to ensure there were no errors creating either the marker or the manager.

Now I use the following:

ZoneStartFinishMM.addMarker(ZoneStartFinishMarkers[idStart], 0);

ZoneStartFinishMM.addMarker(ZoneStartFinishMarkers[idFinish], 0);

And it is tossing an error when trying to add the Markers this way.

Any ideas what's going on b/c I am completely stumped here.

Thanks,

Nathan

What kind of error is being thrown?

have a look at this page which shows how to use the V3 MarkerManager:

http://google-maps-utility-library-v3.googlecode.com/svn/tags/markermanager/1.0/docs/examples.html

because almost everything in the V3 api is asynchronous, the marker
manager isn't ready until it notifies listeners with a "loaded"
event.

Here's a snippet from the examples page:

function setupWeatherMarkers() {

mgr = new MarkerManager(map);

google.maps.event.addListener(mgr, 'loaded', function() {
mgr.addMarkers(getWeatherMarkers(20), 3);
mgr.addMarkers(getWeatherMarkers(200), 6);
mgr.addMarkers(getWeatherMarkers(1000), 8);
mgr.refresh();
});

}

I'm not getting a javascript error per say, my try catch for adding the markers to the marker manager is kicking an error and failing and the markers never show up.

How long does it take for the MM to initialize so I can use it?  Before it was almost instantaneous but now it seems as if it is taking forever.  My function in the c++ that calls the add markers function is getting called several times.

Is there a way to make sure its loaded before I continue on?

I figured out what it was.

I was creating my marker with new google.maps.Marker(point1, MarkerOptions).

My point1 was a LatLng point in google maps.

In the version 3 API, you have to set the point of the Marker by doing position: LatLng and not how it was previously defined in v2 of the API.

Hope that helps someone else out there that may be having a similar issue.

Thanks for the help,

Nathan
