[mapguide-users] Storing WebLayout in Session Repository

[Hidekazu Shimaji]

Paul's advice is a great help for me, but this means that 
I cannot use the MgMap class if I want to change a map 
in initially showing the map, doesn't it?

I agree with Gunter.
It is very complicated, and I also hope a method to show "Map" 
as well as "MapDefinition".
