We ran a script to update some attributes in multiple modules, and along the way a multi-valued enumeration attribute was set to single-valued (multi-value unchecked). Any object with more than one value selected now only has one single value selected. The object's history does not show this change, and the module history only shows that the attribute was modified. Is there a way to undo these changes, other than restoring from a backup?

Its no surprise that when you change the definition of an attribute that there's just one module-level Historyh for it. Notice that you can see there was a change but cannot tell what you did from the History.

Its no surprise that when you change from Multi to Single that Objects now only have one value ..err.. now only appear to have one value; and its not surprise that there is no History since the value of the object hasn't actually changed; yet.

Given what I've see before I'd bet if you change the definition back to Multi that the multi values of the objects will reappear. That should work so long as you haven't actually changed any object values.

Checking the multi-value box didn't restore the values.

Played with it for a while and don't see anything useful.

Looks like you need to have a DXL that finds the last History for an object for that attribute, and if there is more than one value in the History then restore it.
