[mapguide-users] Reloading runtime map

[Jim O'Leary]

Yes, I have seen the Developers Guide sample. However, that code only saves
the layer to the repository. By accessing the XML in the map definition, I
can permanently attach the layer to the map, as well as create the group.
You cannot attach a layer to the map using the runtime map. Thus the runtime
map is not in synch with the repository map, so I need to update the map. 

parent.parent.Refresh()

does not display the new group or layer the properties pane, and 

parent.parent.mapFrame.location.reload(true)

causes the map frame to lose references to the script frame, resulting in
the "freed object" error. Is there another way to update the runtime map?
