Tiered Design With Analytical Widgets - Is This Code Smell?

The idea I'm playing with right now is having a multi-leveled "tier" system of analytical objects which perform a certain computation on a common object and then create a new set of analytical objects depending on their outcome.

In WPF: Children.Remove or Children.Clear doesn't free objects

Update: I tried this on another, more cleanly installed, machine. I could not reproduce this on that machine. If I find out what offending (VSStudio) component causes this, I will let you know.
