Ok I think I have come up with a better solution, on the way home in the traffic jam, it seems simple so I think it will work.
Basically to store a snapshot of the select list in an array element each time before an action is made. For instance user clicks add new element to select list, function add is called, a snapshot of the current data is appended to end of an array then the add funciton is run. Clicking undo just clears the select list and then re-populates with the last array element data then removes it from the array. I guess this is the standard way to do an undo, take a snapshot of the state of the element to be undone, I am thinking an image undo might work like this though I don't know. Anyone see any flaws in my idea?
