Reusable Business Logic and the Application Website
If the field of a mapped cache extension is mapped to a field of the base data access class
(DAC), you can use the merged field (that is, the base field that has merged attributes
of the base field and the mapped cache extension field) to configure the UI elements of
the website page. If the field of the mapped cache extension is not mapped to a field of
the base DAC, you can use the field of the mapped cache extension in the website page,
as shown in the following diagram.Figure 1. Fields on the website page
The actions that are defined in the base graph, generic graph extension, and implementation
class are automatically added by the system on the website page, as shown in the following
diagram. The implementation class can override the actions declared in the generic graph
extension.Figure 2. Actions on a website page
