Note: Probably the editor is just a side effect and is a runtime thing.

I was trying to animate a ProgressBar as its value changes, for that i use a simple Story with a keyframe with a value that is bound to the target progress new value.

The technique worked fine within a page, but when moved into a control it was no longer working.

I checked a similar composition in WPF and a very similar thing happens. The version in plain document works fine, when in control the moment you interact with it it crashes with a name scope issue ( No applicable name scope exists to resolve the name 'ProgressCurveInternal' )

It seems like when the story is in ControlTemplate.Resources it cannot find ProgressCurveInternal. In WPF i can workaround the limitation by moving the animation into Resources of the first child of the template. But in Noesis it is not solved that way either.

I attach both Noesis and WPF projects for reference.

Expected:
Storyboard animation with bindings work the same everywhere
Reports in editor where it is not possible ( if possible with a suggested workaround )

Actual:
Editor seems fine binding things that cannot resolve ( it can be observed the value is 0 when it will not work in runtime )
In page it works fine
In control templates it does not work
