The Bar/Button system has been updated now .. they are now part of the Mixin family which means some of these old functions need to be adjusted in some manner.
For example:
If you had a variable 'b' to hold the actionbutton in question which you then used ActionButton_GetPagedID to customise for your addon ... you now need to customise b:GetPagedID function.
This and many other files will show you other changes that have occurred recently.
