WPF - FindName Returns null when it should not

Question

FindName is broken for me :(

The object I am looking for is there. I have proof.

Here is the scenario:

ToggleButton button = (ToggleButton)s

In my experience, this happens when you add items via code-behind. I've found that you can fool FindName() (or the animation framework) via name scopes. That is, when you create your control, you do

    NameScope.GetNameScope(yourContainer).RegisterName("name of your control", yourControlInstance);

For this to work reliably, though, you must make sure that you unregister the name:

    NameScope.GetNameScope(yourContainer).UnregisterName("name of your control");

Posting this for future reference.
