Hi,
I implemented a refactoring plugin using EMF Refactoring. The plugin refactors EMF model based on a fitness function defined based on metrics. In some cases after refactoring I want to undo applied refactorings. I should probably use BasicCommandStack.undo instruction. I am familiar with this class,but I do not know how and where to get an instance from BasicCommandStack class.

Thanks in advance for your help.

Fazi.

Iman,

Hopefully someone from the refactoring team notices the question. I'll
try to help...

You're sure the refactoring is done as a command? It seems a bit tricky
because I imagine that often multiple resources are affected.

What kind of context do you have. The generated editors implement
IEditingDomainProvider so from the editor instance you can call
getEditingDomain().getCommandStack(). Also, AdapterFactoryEditingDomain
has static getEditingDomainFor methods that can be used with an EObject
to determine its editing domain (by navigating up to the resource set
and finding the associated editing domain for that resource set).

Iman,

I did give the details of how to get the command stack from the editing
domain and how to get the editing domain. Did you try that?

Hi,
Thanks for your help Ed. It works.
I used
EditingDomain editingDomain = AdapterFactoryEditingDomain.getEditingDomainFor(selectedEObject);
to have access to editingDomain. Also I used
editingDomain.getCommandStack()....
to have access to commanStack.

Iman.
