Hello,
I was investigating the possibility to use the undo-redo operations with efxclipse and this package, while available, seems to be of little use without the IWorkbenchOperationSupport, needed to retrieve the IOperationHistory.
This OperationSupport resides in the package org.eclipse.ui.operations, which - if I'm not mistaken - is not available.
I hope till this point, my reasoning is correct?
And if it this, two little questions :
- is there some workaround or should I'd rather create a (series of) context function(s) to take care of (context-bound) commandstacks ?
- For the sake of my understanding of the Eclipse API: could I roughly consider that everything starting with "org.eclipse.ui" has to be replaced, in efxclipse, by an equivalent package org.eclipse.fx.ui, while the packages org.eclipse.e4.ui are ui-independent ?

You need to create your own IOperationHistory and yes most likely
ContextFunction is the way to go.
If you create a bugzilla we can discuss there how a generic
implementation who is shipped as part of e(fx)clipse code look like.
On your second question:
a) org.eclipse.ui: bounds to SWT and bound to compat layer
b) org.eclipse.e4.ui: toolkit independent
c) org.eclipse.fx.ui: I'm a bit indifferent because we've not drawn a
clean line in this namespace, there are bundles in this namespace
who don't dependend on JavaFX and others who do
I think the general rule should be that org.eclipse.fx.ui is bound to
JavaFX.
I guess in this case the stuff we'd develop could even go into a none ui
package org.eclipse.fx.core.commands because it is not bound to any UI
at all!

Another thing we could discuss is if we really want to use the
core.commands API or come up with something new more e4y ;-)
I general the problem is not that hard, you have a stack of commands and
undo/redo methods.
