If I create a new Project, then create and open

I can see an enabled "Undo" item there. It turns out that
it is actually a "Undo Create New Project" action, so if one
selects it, the new projects is of course removed taking the
new diagram resource along with it, closing the editor, etc...
I am not sure if this is a bug or is it the expected behavior?
BTW, who provides for the Undo and Redo global actions?
The generated editor contributes to
<extension
point=" org.eclipse.gmf.runtime.common.ui.services.action.globalActi onHandlerProviders ">
providers for "Save", "Copy", "Paste", etc., but there is nothing
about "Undo" and "Redo".
********************************
The default text editor behaves the same way, so most
likely this isn't a bug. It looks odd to me , though...
Cheers

Marian,
As far as I know this is behaviour deliberately introduced by
https://bugs.eclipse.org/bugs/show_bug.cgi?id=162964. The global undo
context is used when there is no activity in a specific undo context
(which in this case is the undo context for the diagram editor). Note
that this is also the cause of
https://bugs.eclipse.org/bugs/show_bug.cgi?id=173361.
Regards,
Linda

Hi Linda,
thank you for the references.
I agree that the solution they came up with in
https://bugs.eclipse.org/bugs/show_bug.cgi?id=162964.
is a reasonable compromise.
I also noticed myself the problem you described in
https://bugs.eclipse.org/bugs/show_bug.cgi?id=173361.
Thanks for saving me the efford to report it.

Still,
there is a minor glitch to the solution of
https://bugs.eclipse.org/bugs/show_bug.cgi?id=162964 :
When there is nothing in the local history of the fresh editor instance
the menu item label is just "Undo" instead of
"Undo New Project"
