Abstract: An improved model-based approach for undoing actions in an application that was not previously configured with an undo feature is disclosed. Object models are constructed for each object invoked by the application. Snapshots of the object model are captured after every action to preserve the object model state at different points in time. The object model includes an object tree data structure having multiple nodes comprising data and metadata for the object. The object model is frozen and editing of the object is only permitted via an undo management engine. In response to edits from the application, the undo management engine responds by unfreezing the path of object nodes from leaf node to root node in the object tree data structure. Edits are applied to the object model at the leaf node. The object model can then be re-frozen to maintain the state of the object after each action.
