How to execute UNDO in an action?

[crocis]

Hi All,

I have created an action that applies different transformations to an image and saves the different transformed images. In the action, after saving each transformed image I have inserted UNDO using "Insert Menu Item...". Unfortunately, when I execute the action I get the error message "The command Undo is not currently available". How can I execute UNDO in an action? 

Regards,

Simone

Record backing up one history state.

You would need to backup more than one history state. And  Undoing the saved will not delete the save that was done.  You can not undo a save. You need to back to before any transform or modification you made like adding adjustments etc.  Perhaps to Open or a snapshot you make. You need to a keep history state you can back up to.
