Abstract: A method, system, and computer program product for automated binding of an application user interface to the data that it manipulates in an object oriented programming system is provided. In one embodiment, responsive to instantiating an application user interface, a binder object is constructed for at least one component in the application user interface. The binder mediates the exchange of data between the component and the corresponding field in the model. The binder monitors the component for data change events and monitors the model for data change and state change events from the field. The binding is specified by a moniker that is shared by the component and the field. Using the moniker, the binder synthesizes method names to get and set the field value and retrieve the field's state. The binder then locates and invokes, using introspection, the methods in the model that match the synthesized method names.
