[mapguide-users] Reloading runtime map

[Jim O'Leary]

Here is what works:

1. Change the XML for the map in the repository.
2. Make the new group and/or layer in the runtime map using the Web API.
3. Using JavaScript, reload the map frame. From the task pane, this is:

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

Now the new group and/or layer shows up in the Layers pane. When you change
the runtime layer using the Web API, it changes the XML in the repository.
