The system also includes an intermediate object layer comprising an intermediate object associated with the business object, wherein the intermediate object handles user interface messages raised by the business object and retrieves data from the business object for user interface. The system further includes a service manager that provides the retrieved data from the intermediate object for display on the user interface.

Abstract: Methods and apparatus, including computer program products, provided default values for business objects. In one exemplary embodiment, there is provided a method for providing default values for attributes of business objects. The method may comprise receiving, at a first service provider, a call to instantiate a first business object. The method may then obtain a static default value of an attribute associated with the first business object. A second service provider may be called to determine a dynamic default value for the attribute based on the static default value. The first service provider may then be provided with the dynamic default value for use when instantiating the first business object.

Abstract: Business object templates which include a plurality of hierarchically arranged entities and characterize services associated with the entities can be used to generate new business objects. These new business objects are generated based on projections of the business object template. In some variations, the business objects include a subset of the entities defined by the business object template. In other variations, the business objects include all of the entities defined by the business object template but with only certain entities being activated.

Abstract: Systems, methods and apparatus, including computer program products, are provided for saving a plurality of objects to persistent storage as part of a finalize sequence. In one implementation, a computer-implemented method may include, receiving a request to instantiate a plurality of objects; sorting the plurality of objects based on a priority assigned to each of the plurality of objects before the request to instantiate the objects is received; and saving in sequence the sorted plurality of objects to the persistent storage.

Abstract: Embodiments consistent with the principles of the invention check, before the data underlying a changed primary object is persistently save, for related objects whose data is also affected by the change. The related objects may be two or more degrees removed from the primary object. The changed primary object and all its changed related objects are then persistently saved together, so that the saved data is consistent across the related objects. Embodiments consistent with the principles of the invention also provide a state model for controlling access to services by clients and for making services available by servers.

Abstract: Systems and methods are provided for adapting a procedure call from a service manager to a service provider in a computer framework.
