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

I would suggest to avoid using FindName function, based on my experience, expecially problematic when you try to find something in the DataTemplate applied to some control. Instead , if it possible (based on your software architecture) declare Popup in XAML and refer to it like resource or use Binding to set some Model property to it's reference. Good luck.
