I am a having the same problem as listed in this forum: http://www.adobeforums.com/webx/.3bc4ba61. When applying the wiggler to a parameter key frames are made, but nothing changes. I tried deleting preferences, but it still doesn't work. Can someone help?
Funny that this gets reported again every now and then... Well, if the tool doesn't work, why not simply use the wiggle() expression? Should give you all you want and you can convert it to keyframes at any time you like just as well.
