Blender Version
Broken: blender 2.8
a211937892Worked: 2.79
Short description of error
NLA tracks created by script do not animate (ie, scrubbing the timeline does not produce any animation). If, instead of creating an NLA track, the action is simply attached to the object's animation data, the scrubbing does produce the expected animation. The exact same code works well (or at least appears to) in blender 2.79 and earlier.
Exact steps for others to reproduce the error
The attached blend file is setup so hitting alt-p in the text editor creates the NLA track and attaches it to the cube. Scrubbing the timeline will have no visible affect on the cube. If the True on line 19 is set to False, the script will instead just attach the action to the cube, and scrubbing the timeline causes the cube to move 5 units along the X axis, even if the action is manually "pushed down" to an NLA strip.
