No keyframes visible in action editor I had finished animating an action and was previewing it. I accidentally hit R while the animation was playing and not wanting the rotation, I hit escape (and probably a couple of other characters because fat fingers).
Now I don't have anything at all listed in the dope sheet summary. Also there are no keyframe nodes in the action editor. I can still see the animations being done if I scrub the timeline, there's just nothing in the graph editor.
I've tried to figure out how to fix it, but I cannot seem to find it.
Chebhou's response was correct. Make sure "Show Errors Only" was accidentally clicked.
