Copy Commands from one Stack to antoher [message #788094]

Hi,
I have e the following situation.

I have a big Model and one central CommandStack.

Now I want a dialog that works one a piece of the Model.

In the dialog the user should be able to redo and undo his changes.....so I thought of EcoreUtil.copy(modelPiece) with a new own EditingDomain an its own CommandStack on which the dialog works.

At the end I would like to get all commands from the dialog-CommandStack and execute it on the main-CommandStack .

Now the Problem....I dont find any method to get the list of commands of my dialog-commandStack.

Am I blind or is there are better way to the whole thing ?

Regards Markus

Markus,

There's no access to the underlying list of commands; you could provide
that via a subclass. You'd need to paw through the commands in great
detail to replace references to clones with the originals. It sounds
tricky..

Maybe you'd be better to use a ChangeRecorder to keep track of what's
changed and apply those changes...
