Not refresh copy/paste/mirror pose for porxy object?

I have a rigged character and i linked from an other library and make the armature a proxy object but when i use copy/paste/mirror pose buttons the mesh not will refresh just the armature (the mesh not a proxy object) for fixing it i need insert a key or turn on the automatic insert key but i would like use without insert keys as in normal way.
This is possible somehow or im miss something?

This is a bug, and I’m experiencing the same thing. You can actually get the mesh to refresh by selecting any bone and hitting one of the transform keys (like the G-key). Then use the RMB to cancel. That’s what I’ve been doing.

Thanks for suggestion Harkyman.
