Comment 2 Sergey Petrov 2008-11-13 12:07:45 UTC 
//investigation: initial reason is fail to duplicate attribute:
CreationFactory can't create empty Presentation elements, reasons are unknown yet. may require extra time. it may have
sense to disable copy action in project tree for now (move will remains), thi way attributes/operations will work
exactly the same way as all other elements (all elements support move only in rpoject tree).
