You can add an ADF-bounded task flow to a page as an ADF region. The ADF-bounded task flow must be created using page fragments, not pages. A page fragment is a JSF JSP document that can be rendered as content of another JSF page. It is similar to a page, except that it cannot contain elements such as <f:view>.
An ADF region appears as a subarea on the page. Shopping Cart is an ADF-bounded task flow exposed as an ADF region on the Fusion Order Demonstration (FOD) application Home page. The task flow contains a single View activity summarizing the contents of the cart. The region drives the presentation of the Shopping Cart ADF-bounded task flow as it executes on the page.
