4.1.3 Handling of PAOs Within the Client

All PAOs and PICIs are mapped onto internal components of the client framework (list, table, etc.). Result input components (components that deliver the result of a PROGRESS server computation) are dispatched to the presentation layer, whereas the PAO interface and the request input components (the PICI that is instantiated within the PAO at bootstrap time) are dispatched to the interaction layer of the GUI. The use of internal framework components leads to the uniform look and feel of the user interface.
