Strange Issue with "Recent" Stacks in Mountain Lion After my recent upgrade to Mountain Lion I accidentally dragged the &quot;Recent Applications&quot; stack off the dock and it &quot;poofed&quot; 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 '{ &quot;tile-data&quot; = { &quot;list-type&quot; = 1; }; &quot;tile-type&quot; = &quot;recents-tile&quot;; }'

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 &quot;Recent&quot; 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?
Issue solved:  After the update the Recent Items selection in System Preferences>General was set to 0.
