Embodiments of the present invention provide a method, system and computer program product for the auto-completion of values in a model in a composite services enablement data processing system. The method can include establishing for a common session, multiple channels of access to a model for a composite service. The method further can include synchronizing views for each of the channels of access based upon detected value changes to data members of the model. Finally, the method can include auto-completing associated values for other data members of the model responsive to receiving a value change for one data member in the model.
