Earlier we had discussed the usage of task flow call activity for displaying a bounded task flow built with complete JSF pages. Bounded task flows built with page fragments are displayed by using an ADF region (af:region) component.
The ADF region is a place holder component that
allows dynamic contents to be included in the parent page. When you run a page with a region, the region component peeks into the underlying oracle.adf.view.rich.model.RegionModel for identifying the view to be displayed and instantiates the view. In general, ADF uses the af:region tag to display bounded task flows built using page fragments. ADF allows you to embed a region in a page or page fragment. Note that regions are capable of triggering the navigation of contents in its own display area (view port) without affecting the other regions or parent page. This is the reason why you are able to navigate between pages in bounded task flow added inside a region, keeping...
