Please, before you open layout and map in Maestro go to: http://localhost/mapguide/mapagent/index.html -> go to Resource-->GetResourceContent--> and type correct resource ID on right side. See is there any strange things in output XML file. Compare it after saving it in Maestro.

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.
