When I flush the caches everything works correctly on the first page load. After loading second page (any page will do) I get this 'Uncaught TypeError: Cannot call method 'addHandler' of undefined' error in my console. The reason for this is that the Drupal.gmap has somehow disappeared from the js object. Here is the output from console after first page load (https://skitch.com/ilari/8u6dm/gmap) and after second page load (https://skitch.com/ilari/8u6d1/gmapgone). Any ideas?
