Hi! Could one please review my commit r390142 (see commits@).
It is a try to throw an exception if one add more then one child to a facet. I've done this after I 2 hours of searching a problem in our application just to figure out it was due to multiple facet children. The if (id....) stuff is required during restoreView. It turns out to work here, but its a deep change so I wanted to inform you about it. So we can early remove it if it was a bad idea ;-) Ciao, Mario
