ID 156766 - Keyframes are not updated on the SplineWarp 'root warp' knob when a Nuke script is reopened

Problem summary
Keyframes are not updated on the root warp knob of the SplineWarp node when a Nuke script is reopened.

Customer reported version
Nuke 14.0v5
 

Customer reported platform
Windows 10
 

Steps to reproduce

1) In Nuke, create a SplineWarp node.

2) Add a Bezier and set two keyframes on the root warp knob.

3) Save and close the script.

4) Reopen the saved script and observe the root warp knob value for animation.

Expected behavior
The root_warp keyframes should be updated and keyframe animation displayed as the script is opened.
 

Actual behavior
When reopening a saved script, the SplineWarp keyframes are not updated for the root warp knob, and the animations will be destroyed if setting a different value before selecting a spline.
 

Workaround
Select a spline in the SplineWarp node before adjusting any values.
