Hi!
I have updated australian 4.2.2 firmware to my Galaxy Tab2 and have the exact same issue.
The only workaround I found is to go edit mode on homescreen then rotate your device. For me this way the dock appears and one action can be done. By repeating the rotation before each action I managed to change the dock icons. It is a pain but worked.

 Also worth noting for those of us who thought we were stuck with those specific apps, that you can also drag other apps onto the dock before it disappears which is very handy.
