GoogleMap Plugin
Since 2.92, GoogleMap supports loading on the fly.
How to use
Really easy :
PluginManager.getInstance().declarePlugin('GMap', 'http://maps.google.com/maps?file=api&v=2.x&key=myKey
&c&async=2&callback=ModelHelper.getInstance().mapLoad()', 'GScript', '', true);
Note that you will have to replace myKey by the key corresponding to your website and ModuleModel.getInstance().mapLoaded() by the method that has to be launched after the map is loaded (ModuleModel is the name of your model helper).
