Using a Single .jspx with Regions
You can add an ADF-bounded task flow to a page as an ADF region. A region is a UI component whose content is based on a task flow definition. When it is first rendered, the region’s content is that of a first view activity in task flow.
Any view activity used in the region 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 it cannot contain elements such as <f:view>. An ADF region appears as a subarea on a page.
