[mapguide-users] Add new layer to map

[sekko970]

Dear Kenneth,
I need your help for a second problem:

I apparently save successfully the new layer into library repository (the
legend and the map are correctly updated, and from MGStudio the new layer is
visible in layers list), but in MGStudio 'Layer by group' view, my layer
doesn't appear, so that when I reload the map, the new layer is lost (but
it's present in MGStudio).

Have you some idea?
Thanks, Fabio
