remove undo and redo actions ? [message #229896]

Is it possible to remove the UndoAction and RedoAction from the context
menu of a GEF Diagram editor?

I've tried commenting out the following bit of code in createActions, but
this results in the context menu not being displayed at all:

// action = new UndoAction(this);
// registry.registerAction(action);
// getStackActions().add(action.getId());
//
// action = new RedoAction(this);
// registry.registerAction(action);
// getStackActions().add(action.getId());

I also tried leaving the above code in then using removeAction, but this
has the same effect - no context menu is displayed:

action = registry.getAction ("redo");

if (action != null)
{
registry.removeAction (action);
}

Thanks in advance,
Mark Robinson

I've sorted this. I was adding the undo/redo menu items myself in a
ContextMenuProvider - oops !
