MyEclipse: GoogleMapsExamplemaking call to non-existent addOverlay()

Post subject: GoogleMapsExamplemaking call to non-existent addOverlay()
The GoogleMapsExample is making call to non-existent function map.addOverlay(marker) in map.js . It looks like the example is using the deprecated addOverlay(). I should be using marker.setMap(map)
See: http://code.google.com/apis/maps/documentation/javascript/overlays.html#AddingOverlays

This example if you add Spring MVC functionality you end up with the following server side exception which results if a javascript non-existent function and the spring dojo has been loaded.

eddybell,

Quote:

The GoogleMapsExample is making call to non-existent function map.addOverlay(marker) in map.js .
Let me clarify that the map.addOverlay function is a googleMaps function. Please refer google.jsp.
Code:

<script type="text/javascript"
         src="http://www.google.com/jsapi?key=ABQIAAAA7rD1jbUY1XVWsL0ov0bKehRP189eykzPrrAV7tRgT92eURxrGxQHDNt6Nc2DQaubssvpI9493dhTGg"></script>
      <script type="text/javascript">
           google.load("maps", "2");
           var map = null;
           var geocoder = null;
           google.setOnLoadCallback(function initmap() {
              map = new google.maps.Map2(document.getElementById("map"));
              geocoder = new google.maps.ClientGeocoder();
           });        
      </script>

This remotely loads the relevant googlemaps javascript to your clientside. To verify, I would recommend you run GoogleMaps example using sandbox/MyEclipse tomcat.

I would recommend you debug your application. It looks like it is missing a parameter named idKey.
If you need help with google maps api, here is one such tutorial - http://econym.org.uk/gmap/

Unfortunately it looks like you looked at the V2 API documentation not the V3 which is the currently Google supported API I have included some relevant links
google search string "addoverlay google maps v3 deprecated"
http://code.google.com/apis/maps/documentation/mapplets/overlays.html

eddybell,

Thank you for the links. Please note that even if addOverlay method is deprecated, it can be still used. I do not think that the issue you are referring above is a result of the addOverlay method being deprecated. Have you tried to debug your application?

Post subject: RE: GoogleMapsExamplemaking call to non-existent addOverlay(
I have included dump from the firefox js debugger which shows the addOverlay as undefined. In a JS only page this is not an issue because an undefined function does nothing but if dojo has been loaded then you will get the error as above because dojo tries to lookup the addOverlay on the server side. All you need to do is run the sample and try and step into the addOverlay and you will find that it is undefined

Eddy,

I have not tried this example in some time, but I did today and it worked fine.

If I comment out the map.addOverlay method in map.js, then when I look up an address, the map shifts to the position that I keyed in, but no marker is added at that point.

If I put the line back in, the marker appears.

I did not attempt to debug the code, but empirically, the addOverlay method seems to be alive and working as originally intended. Have you tried it in an unmodified project, before adding Spring MVC etc?

Nevertheless, since the method is deprecated, we will use the newer method when overhauling the example code, I have filed a bug for this, thanks!
