I am building an AF Database from existing element templates. This I am doing from C# and the PI-AF SDK. I've noticed that in an empty system not all elements get created - which cause an additional problem if a parent fails to be created. I'm checking-in the updates every few entries (overkill) and yes, I am refreshing the displays in PI System Explorer. If I reurn the program then the 'missing elements are sometimes created. If I delete the entyries and start again different elements are sometimes missed out. Moreover if I step through the program in debug or place a few debug points in the main code everything appears okay. So it's as if my program is too fast for AF.
