After my recent upgrade to Mountain Lion I accidentally dragged the "Recent Applications" stack off the dock and it "poofed" away... not that big a deal, I just went into Terminal and used the following command
defaults write com.apple.dock persistent-others -array-add '{ "tile-data" = { "list-type" = 1; }; "tile-type" = "recents-tile"; }'
followed by resetting the dock with
killall Dock
exit
Then emptied the trash, shut down, and reboot for good measure...
A space for the Recent Apps is now present on the dock, but it doesn't contain anything, no matter how many apps I open. It is right clickable to get the context menu. The same is true no matter which kind of "Recent" stack is selected. If selected the Favorite Volumes or Favorite Items stacks work normally.
Looking through the Library there is no recent items plist.
What's my next step?
