[news.eclipse.tools.gef] Undo with keyboard

[Arnaud <arnaud@xxxxxxxxxxx>]

I cannot undo in my gef editor with keyboard but I can delete

I create a keyHandler :

keyHandler = new KeyHandler();

keyHandler.put(KeyStroke.getPressed(SWT.DEL, 127, 0),
	getActionRegistry().getAction(ActionFactory.DELETE.getId()));

keyHandler.put(KeyStroke.getPressed(26, SWT.CTRL),
  	getActionRegistry().getAction(ActionFactory.UNDO.getId()));

keyHandler.put(KeyStroke.getPressed(25, SWT.CTRL),
	getActionRegistry().getAction(ActionFactory.REDO.getId()));


and I reference it in my configureGraphicalViewer method :

GraphicalViewerKeyHandler keyHandler=new 
GraphicalViewerKeyHandler(getGraphicalViewer());
		keyHandler.setParent(getCommonKeyHandler(getGraphicalViewer()));
		getGraphicalViewer().setKeyHandler(this.keyHandler);

It works fine with the delet command but doesn t seem to run with the 
undo/redo

thx
