Hi Jacek, Sorry, I missed your point. You want to use multiple virtual inheritance. Before doing so, we have to evaluate all possible consequences and side-effects. Coming back to your question in 1997 (::) , this problem is now solved since all collections can be named. Use TCollection::SetName when you want to name a collection. (and GetName).
