[mapguide-users] Create programmatically a map

[sekko970]

Hi Kenneth,
I need again your help about my problem.

I think the problem is that after new map run-time creation in library
repository, I cannot use its map definition to create its web layout.

How can I assign the new map to the layout?

Thanks again, Fabio
