A method and system for updating templated application design, which facilitates the later ‘undoing’ of the design update is provided. The method intercepts all design update requests and automatically creates and stores a description of the pre-update version of the application. When a developer intends to apply an update to a design of an application, the application is first asked to provide a description of itself, e.g. a template. If the application comprises a plurality of components, each application component provides a description. Thus a point-in-time design description of the application is created. This is stored and can later be used for an undo method or even multi-level rollback, as required.
