[mapguide-users] Create programmatically a map

This is my problem:

I have created programmatically a map (and its layout) using MG .Net web
API. 
After creation, the new map and layout are visible in MG Maestro, and using
the 'Show in browser" button are correctly shown in browser. 

The problem happens when I load the map directly from browser, and the
following error appears: 
<< The type 'OSGeo.MapGuide.MgNullArgumentException' in assembly
'MapGuideDotNetApi, Version= 2.0.2.30 11, Culture=neutral,
PublicKeyToken=null' is not marked as serializable >>. 

Then, simply saving the new layout from MG Maestro (without any
modification), and reloading the map directly from browser, the error
disappears and the map is correctly shown. 

After saving the layout, there aren't differences in map and layout XML
definitions. 

Have you any idea about?
