Subject: [mapguide-users] Force Refresh of Layers

When some feature is inserted/updated dynamically in a feature 
source, what we have to do to programmatically force the refresh of 
all layers affected in all active map sessions ?
This in case of using DWF Viewer to view the maps. When using Ajax 
Viewer the refresh is done automatically.
