I am trying to activate the global undo/redo menu items for a specific
EditorPart. This works nicely as long as I let my editor active, but
when I switch to another view in the workspace, the whole undo mechanism
seems to be "forgotten" and only shows deactivated undo/redo actions.
Apparently there is something wrong with the way in which I install the
actions. Does anyone know what I am doing wrong - relevant code is below:
EditorPart myEditor = ...;
IUndoContext undoContext = new ObjectUndoContext(myEditor);
UndoRedoActionGroup group = new UndoRedoActionGroup(myEditor.getSite(),
undoContext, false);
group.fillActionBars(myEditor.getEditorSite().getActionBars( ));

If you need to do your action work programmatically, would you not use
ActionBarContributor subclass (that way every time your editor becomes
active, your actions will be activated)?

Yes, this is working. I am now calling the group's fillActionBars
method each time my ActionContributor's setActiveEditor method is called.
I really appreciate your help - this saved me a lot of time!
