Converting a Bounded Task Flow to Use Page Fragments
When you are initially developing a bounded task flow, you may use view activities that correspond to pages (.jspx). However, to use a task flow as a region, the view activities cannot be full pages, so you can convert the task flow to one that uses page fragments. You have to only right-click a blank space on the task flow diagram and select Convert to Task Flow with Page Fragments.
This converts all pages associated with view activities in the bounded task flow to page fragments. You can optionally save old pages by selecting the Keep Page? check box. New page fragment names default to the names of the old pages. For example, MyPage.jspx becomes MyPage.jsff.
