[mapguide-users] Session Map and Settings Serverside

[Rock Beans]

Is there a GetLegendFrame() viewer command? There seems to be one for
everything else. I need to refresh Legend and I don't want to hard
code but if needed will do. I got the map doing what I want with
layers and scale. Then call ZoomToView with refresh = true. That
should in my mind refresh the legend tooooooo. Why does it not?
