i’ve been unsuccessfully attempting to create my own undo/redo classes that work well with any type of possible undo and redo commands.

for example, my simple class works perfectly with undoing/redoing x and y positions of display objects or undoing/redoing values of sliders, etc., but things get dicey when i try to tailor my classes to also work with things like adding and removing items to a list.

is there any well known and well documented solution for general undoing and redoing for actionscript (without Flex)?

    you can also check Command pattern, which is the de-facto standard ,irrespective of the programming language, it would give you the basics.
