The "problem" in my case is, that I don't have a special edit mode, I display the information, and it can at the same time be altered by the user. Furthermore, it is a dynamically created layout with no _single_ point of exit. It had been so nice, if the dirty flag would have been accurate, and promoted through the hierarchy - a face get dirty, whenever one of its subfaces gets dirty, if a parent face gets the dirty bit cleared, all subfaces get it cleared, too. Kind regards, Ingo
