Ok,
I got this sorted out. It was my own programming error, though I can't 
understand how this can make the whole system to break. This was called 
way before the exception point:

     public void ClearDataSource(IServerConnection conn, String 
dataSourceId, String featureName, string idField, List<int> laiteidt)
     {
         foreach (int laiteid in laiteidt)
         {
          IDeleteFeatures deleteCmd =    
(IDeleteFeatures)conn.CreateCommand((int)OSGeo.MapGuide.MaestroAPI.Commands.CommandType.DeleteFeatures);
          deleteCmd.FeatureSourceId = dataSourceId;
          deleteCmd.ClassName =  featureName;
          deleteCmd.Filter = "ID >= 0";
          int nDeleted = deleteCmd.Execute();
         }

It should have not been "ID >= 0" but 'idField + "=" + laiteid' 
(remainings from old stuff..). This was called at line 1918 and 
SetResourceXmlData() much later in a whole different method at line 
2100+..

Actually I can't figure out how the unsuccesful 'Delete' with wrong 
attribute name can prevent from saving layer definiton..?
Should have been put into try/catch I guess..
