GoogleMaps JSP Tag Library
Tag event

Adds an event listener to the parent tag. This tag can only effectively be a child of a <googlemaps:map> or <googlemaps:marker> tag. If a child of any other tag, this tag will register itself with the next highest instance of <googlemaps:map> or <googlemaps:marker>. When a map or marker with a registered event is triggered, the URL is called additional parameters based upon the parent component type and the event that is triggered.

The intended use is to have the event trigger a request to either a servlet or JSP page. This page would retrieve the map from the session using the map id (passed as map parameter) making the required changes, additions, etc. and then pass the response back to the requesting page or another page that displays that map, which would then render the map with the changes.

For this methodology to work properly, the parent map must have a scope of type site, so the receiving entity can locate the map from the session.
