[mapguide-users] modifying map before the WebLayout loads

[Kenneth, GEOGRAF A/S]

I realise that the supplied code is just a snip of the actual code, but 
the overal procedure should be:
Create session
Load MapDefinition
Modify MapDefinition as needed
Save MapDefinition in session repo
Load WebLayout
Modify WebLayout to point to session map
Save WebLayout in session repo
Open viewer pointing to WebLayout in Session repo

If you modify any layers, you must also save those to the session repo, 
and update the MapDefintion to point to those.

Below I think you are saving a runtime map, rather than the MapDefinition.
I belive the viewer will overwrite any existing runtime maps.
