If you are using dynamic pages, then you typically also think about dynamic adapters.
Let us take the example of a generic maintenance application for table records in which the detail screen of a record is dynamically created. Having the dynamic screen is the one part of the story; having a generic adapter providing for exactly these properties that are belonging to the records is the other one.
Application Designer offers a powerful way to provide for dynamic adapters. See Binding between Page and Adapter for detailed information.
