Some of my news items have maps in them, though they are not visible in the summary view. It seems, however, that the module is trying to initiate all the maps anyway. I'm not sure who exactly is responsible for this problem (Views or WYSIWYG_Map) but I fixed the problem as follows (sorry I don't know how to create patches) js/wysiwyg_map_token_maps.js - line 52 Old // Create the map and drop it into the relavent container. map[i] = new google.maps.Map(document.getElementById("wysiwyg_map_" + map_collection[i]['container_id']), mapOptions); // Add the marker to the map. marker = new google.maps.Marker({ position: latlng, map: map[i] }); New // Create the map and drop it into the relavent container. var mapContainer = document.getElementById("wysiwyg_map_" + map_collection[i]['container_id']); if (mapContainer) { map[i] = new google.maps.Map(mapContainer, mapOptions); // Add the marker to the map. marker = new google.maps.Marker({ position: latlng, map: map[i] }); } Files: CommentFileSizeAuthor #1 wysiwyg_map_token_maps.js_.txt2.08 KBmarkgp Comments Comment #1 markgp CreditAttribution: markgp commented April 4, 2013 at 3:10am FileSize wysiwyg_map_token_maps.js_.txt2.08 KB Some more problems cropping up, this time when using the Views UI to edit a view that would display content with a map. The following error appears when loading /admin/structure/views/view/[view_name]/edit:ReferenceError: google is not defined Also, clicking links that would normally produce a Views dialog box (eg: editing a field) produces the following javascript error: TypeError: google.maps.LatLng is not a constructor http://maps.googleapis.com/maps/api/js?sensor=false - line 12 Updated javascript file is attached. Edit: Disregard attachment (wheres the delete option?), spoke too soon on my fix. Still investigating.
