Looks to me like Undo can be a bit tricky with 4D Write Pro. For example if I add an image to a WP area with WP Add Picture and then hit command-Z it dutifully removes the image. If however I change the image using WP SET ATTRIBUTES(imageRef;wk Image;myPicture), a Command-Z will cause the Image to be removed. Whatever mechanism is storing the undo chain is apparently not recognizing the SET ATTRIBUTE command.
I am guessing that this is much like the saving of a c_object in a record where the record is not set dirty when a child parameter us updated unless you do something else to make it dirty like [mytable]mycobjectfld:=[mytable]mycobjectfld John Baughman 1331 Auwaiku Street Kailua, Hawaii 96734 (808) 262-0328 john...@hawaii.rr.com ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **********************************************************************
