Error with bone and shape key animation

Could you provide an example of what you are trying to achieve? I do not understand why you are trying or wanting to use shapekeys with bones? Typically you would animate keyframes of your bones and this would control the animation of your mesh. Now with that said…I guess I could come up with some wild ideas…but your next questions has me more perplexed…you are wanting to set shapekeys animation with bones…. So in this case you have a object that you have control over with shape keys….then you are adding a bone to that shapekey controlled object and wanting the bone to influence the shapekey object in addition to the shapekey control? My thoughts are you have a sphere and you want it to transition to a cube…so you create a shapekey system…now you want that shapekey to have bones so you can bend it?
