%%%I currently do a larger project with many mechanical stuff and moving parts, so I tried to break up and sort out individual animations into many smaller libraries which are then linked into larger libraries adding the smaller animations together to one large rig. The problem arises with the second level libraries whose animations aren't visible in the main scene, the original data and actions from that libs are visible in the dope sheet but no animation shows up in viewport.

Example: Robot

Main scene: Linked in animatable robot in environment
Library 1: Complete robot rig, limbs are linked in from deeper library level because they have individual detail animations
Library 2: Animation of the details of one limb (think of rotating gear wheels)

It appears that the detail animation of the limbs from the second level aren't passed to the main scene or aren't evaluated there anymore for some reason.

I have attached an example scene with a very simple rig group linked via two levels into the main scene, when I there press Alt+A I would expect the cube to move. Would be nice if this could be fixed.

I'm on windows 7 64, tested with official release.

%%%Issue confirmed... Campbell, do you have a hint here?%%%

%%%It's a depsgraph issue, more my area. Fix in svn revision 60222, thanks for the report.

By the way, there's some strange things in these files. In lib_level1.blend you assigned an action to the cube, but this contains armature bone animation, so it will do nothing as the animation channels don't map to anything in the mesh object. In main_scene.blend that action is assigned to the dupli empty, and also will do nothing. Probably that was just done for testing to try to get this working.%%%

%%%Yes, the assigned actions are leftovers from testing. I tried a workaround in the first level lib by reassigning the action to a proxy of the linked in armature from the second level. Thanks for the quick fix, just in time.%%%
