Hello all, We (Soph-Ware Associates) have just released an Open Source Undo/Redo Framework for Flex. It integrates tightly with Cairngorm and allows for an unlimited number of Undo/Redo events (which in turn fire undoable Cairngorm Commands).
The Flex UndoRedo Framework is lightweight and can usually be used with existing command classes without any necessary changes. For more information, see the following links: http://blogs.soph-ware.com/?p=5 http://code.google.com/p/flexundoredo/ And as everybody loves examples: http://blogs.soph-ware.com/posted-content/files/undoredo/CairnCalc/ We'd love to hear from you, so if you have comments or suggestions please let us know! Thanks. Kaleb Pederson http://www.soph-ware.com/
