[mapguide-users] Reload layer who are stored indatabase...afteradd new polygons.

[Maciej Skorczewski]

hi Traian !

how can i make it (clear the tile cache) in ajax viever whit tiled base 
layer? How to load it again whit new (updated datasource in postgis 
database)

ps. when i try this on vector (no use of tiled base layer) i get this 
same result but - alter zoom in, and zoom out ,new object was added to 
map. But still problem whit reload layer in actualy view (zoom scale) (i 
can make only on-off visibility of layer to see results but this is not 
nice solution) .I use tiled base layer becuse it is much faster...
