Let me clarify this. You can do layer/group toggling via the overlayimage URL route. If you look at the bundled OpenLayers examples, you can see the requests that are made when you toggle a layer or group on/off in the legend.
If you want to do this "silently" without requesting a new map image, then that is not currently possible as there is no dedicated URL route for that. The closest possible workaround would be to request an overlayimage that will return the smallest possible information (behavior=1, format=png8/jpg), and just discard the response. This is similar to my documented technique of modifying MgMap state: http://themapguyde.blogspot.com.au/2013/05/an-elegant-mgmap-hack.html - Jackie -- View this message in context: http://osgeo-org.1560.x6.nabble.com/mapguide-rest-feedback-tp5168657p5170073.html Sent from the MapGuide Users mailing list archive at Nabble.com. _______________________________________________ mapguide-users mailing list mapguide-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapguide-users
