QCMagritte question- does it have undo?
I've never used magritte or QC magritte and was wondering whether with the momento it qas also possible to get multi step undo cheaply if it didn't already exist. Thanks Paul

I don't know if it exists. But you just need to save the current memento, copy it (make sure the dictionary inside is another instance) and use that. This would work before a commit has been done. Do you want to undo even commited stuff? Norbert
Thanks Norbert. I'm not sure of the feasibility/value but I think it would be nice to be able to undo back to a clean slate and redo all the way to a fully fleshed out system. Or at least some sane way in a multi-user environment. I wonder how etherpad.org has their undo structured. I'll go check it out. Paul NorbertHartl wrote

Paul there is an undo framework inside Pharo I imagine that you can use it to build your ideas. Stef Le 11/11/16 à 18:31, Paul DeBruicker a écrit :

There is no explicit support for multi-step undo. In QCMagritte we have support for non-dictionary mementos, and we mostly use that to create actual model instances instead (with reduced validation constraints). That facility might be a good place to add multi-step undo easily. Stephan
