How to reproduce the bug? I wanted to add an change to the undomanager stack . var components = editor.Components; editor.UndoManager.add(components.getComponents().models);

What is the expected behavior? The change added using um.add() should be added ..and when i press undo and redo this change should also be displayed.

What is the current behavior? The change is not added.
